Fill in the bottom line of DNA with the complementary base pair:
Answer: ACCTGATCGTAGCT
Explanation:
Keep in mind that in DNA replication, the matching base pairs are A and T (adenine and thymine) and C and G (Cytosine and Guanine). This means that for DNA complementary strands, A's can ONLY bind with T's and C's can only bind with G's , and vice versa. So, your answer for the picture you have given is ACCTGATCGTAGCT

15. Assuming the fluorescence threshold is set to be 1. Which gene has the highest gene expression rate? What is the Ct value? Gene with highest expression = ______________ Ct value = _______________
Answer:
The correct answer is - Gene 1 and 14.5 (or 14).
Explanation:
The cycle threshold is denoted as Ct value. It is the cross point at the threshold line meets with fluorescence signal reaction curve. In the given RTpcr experiment, the threshold line is fluorescence intensity 1 thus, Ct value for each gene will be the point at which each curve meets the fluorescence intensity line at 1. Ct value of is inversely proportional to amount of nucleic acid in the given sample.
Here, the Ct for gene 1 is the lowest, so the amount of DNA would be highest.
Gene with highest expression= Gene 1
Ct value= 14.5

Answer:
D
Explanation:
Have a nice day
Eukaryotes are different from prokaryotes because only eukaryotes have Organelles. The correct option is C.
What are prokaryotes?Prokaryotes are primitive organism that is single-celled and their cell contains a capsule and flagella or cilia for locomotion and finding food. These organisms lack true organelles.
Eukaryotes are organisms that can be single-celled or multi-celled. They contain the true nucleus and organelle in the cell and the cell is covered with a cell membrane and a nucleus is present that contains the DNA or the organism.
Prokaryotic and eukaryotic cells, both contain DNA, a plasma membrane. But in prokaryotes, an organelle is absent, and they are covered by a capsule.
Thus, the correct option is C. Organelles.

Why does each trophic level have a smaller amount of organisms or biomass than the one below it? A. Because higher trophic levels have lower survival rates for offspring. B. Because each trophic level has larger organisms than the one below it. C. Because the higher trophic levels have to hunt the lower trophic levels, so they- use most of the energy that they gain from eating. D. Because each trophic level is only absorbing 10% of the previous, so there is not enough energy to sustain larger numbers.
Each trophic level has a smaller amount of organisms or biomass than the one below it because it is only absorbing 10% of the energy from the lower level, so there is not enough energy to sustain larger numbers.
A trophic level refers to a level in the food chain consisting of the same or biologically similar organisms. Examples of trophic levels include producer, consumer, and decomposer.Organisms in the lower trophic level serve as food for organisms in the next trophic level of the food chain.Only about 10% of the energy derivable from one trophic level gets to the next trophic level, the remaining is lost as heat during metabolic processes.Hence, the number of organisms progressively decreases as we climb higher in the food chain. The limit to the amount of energy transferred as we move higher means that the number of individuals that can be sustained will also be limited.The correct option would, therefore, be D.

Which of the following factors would LIMIT carrying capacity?
A. Far from factories or roads
B. A large nearby river
C. Abundant food
D. A small space to live in
Answer:
D. A small space to live in
Explanation:
Having a small space to live in would directly limit carrying capacity.
Since there is a small space, only a few organisms would be able to live in that space.
This means that carrying capacity is limited, because the space does not have enough room to sustain more people.
So, the correct answer is D. A small space to live in

In sweet peas, the genes for flower color and pollen grain shape are 11 cM apart. A pure-breeding purple flowering plant with round pollen grains is crossed to a pure-breeding red flowering plant with long pollen grains. The resulting F1 offspring are all purple flowering plants with long pollen grains. What percent of offspring from a test cross analysis of the F1 individuals would you expect to be purple flowering plants with long pollen grains
Answer:
The correct answer is - 44.5%.
Explanation:
In this question, there are two traits are given, flower color and pollen shape. The purple flowers and long pollen are wild-type (dominant). Red flowers and round pollen are mutant or recessive. The cross is between a pure breeding purple and round pollen plant with red and long pollen plant. The offspring are all purple and long pollen plants. However, the offspring would be all heterozygotes genotype for both traits.
Linkage can be calculated as -
Linkage distance = % of recombinant offsprings formed in a test cross.
parental types are purple and long pollen, red and round pollen.
So, the recombinant type would be purple and round pollen, red and long pollen.
11% of the offspring would be recombinant type as the distance is 11cM. Therefore, 89% of the progeny would be parental type. Which means this 89% of parental offsprings have equal proportions of both phenotypes of parents. So, the purple flowers and long pollen would be half of 89%.
that is 89/2 = 44.5%.

A population of 100 sea stars is in Hardy-Weinberg equilibrium. The trait for long arms is completely dominant to the trait for short arms. In this population, 40% of the alleles for this trait are dominant, and 60% are recessive. What percent of sea stars in this population are heterozygous
Answer:
In population genetics, the Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences
Explanation:
An allele frequency is computed by dividing the total number of copies of all the alleles at that specific genetic locus in the population by the number of times the allele of interest is observed in a population. The decimal, percentage, or fractional forms of allele frequencies are all acceptable.
What sea stars are in Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium, model, theorem, or law of population genetics states that, in the absence of additional evolutionary factors, allele, and genotype frequencies in a population will remain constant from generation to generation.
Therefore, The lesson and figure 12.12's allele frequencies are used in this question as well. The percentage of individuals with two dominant arm length alleles can be calculated by multiplying 0.6 by 0.6. The population size (100 people) multiplied by that percentage yields the number of people that are homozygous dominant for the arm length allele.

From a chemical view, how is an amino acid is being recognized by its specific aminoacyl tRNA synthetase?
Answer:
An aminoacyl-tRNA synthetase (aaRS or ARS), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.

Guinea pigs can produce different coat colors, white, brown, and mixed white/brown (agouti). The allele B is codominant with allele W (white coat). Cross an agouti-colored Guinea pig with a brown Guinea pig. What are the odds of the offspring?
Answer:
Brown
Explanation:because the agouti itself is a mixture that remains of a pale brown color and the melanin content in the animals is in the darker colors so it is more likely that the brown color is predominant to the agouti due to the content of melanin that it
The descendants of a cross between an agouti heterozygous (AB) colored Guinea pig and a brown (BB) colored Guinea pig are half heterozygous agouti, half homozygous brown. The correct option is A.
What exactly is codominance?Codominance is a genetic effect that happens whenever the alleles are expressed in heterozygotes.
In this particular instance, allele B co-dominates with allele W, resulting in heterozygous (WB) colored Guinea pigs like one of the parents.

beaker filled with a 40% salt solution. Assuming that water can pass through the
small pores of the dialysis bag, whereas the large salt molecules cannot, what will
happen to the size of the dialysis bag?
Answer:
The bag will get smaller
Explanation:
Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.

In the cell bio lab, we use company manufactured gels, however you can make you own polyacrylamide gels. List all of the ingredients found in an SDS-PAGE gel. Which ingredients are responsible for polymerizing the solution?
Answer:
The list of ingredients are used in this method are as follow-
1. Acrylamide - mostly 30%
2. Bisacrylamide - mostly 0.8%
3. 1.5M Tris-Hcl pH 6.8 for stacking gel and 8.8 for separating gel.
4. 10% SDS
5. 10% APS
6. TEMED
7. Double distilled water
Polymerization:
Acrylamide is a polymer that is used to dissolved in buffer and bisacrylamide is the cross linking agen.
Two types of gels are prepared for separation of protein. Stacking gel is usually 4 or 6% and separating gel is usually 10 to 20%. Lower concentration of stacking gel will allow the migration of all the protein same because of larger pore size. It will stack or line up the proteins for its next level of separation.
Higher concentration of separating gel will provide resistance to the movement of protein because of the low pore size and therefore linear bands can be achieved neatly.
