Transcription is the process of mRNA synthesis. It occurs in the nucleus before translation. During transcription, RNA bases pair DNA bases, replacing Thymine with Uracyl. You will find the example in the explanation.
Note: The DNA sequence is missing, so I will provide a new sequence and explain the procedure. I suggest you perform the same steps with your molecule fragment and reach the correct mRNA.
Protein synthesisProteins synthesis is done in two stages: transcription and translation. The whole process begins in the nucleus and finishes in the cytoplasm.Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA. Once the new molecule is completed, it is sent to its final destiny.Transcription:The first step before protein arrangement is to synthesize messenger RNA, mRNA. This is the transcription process and occurs in the nucleus. When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand. The coding strand goes in direction 5' to 3', while the complementary strand -template strand- grows in direction 3' to 5'. This last segment is the one that is going to be complemented by the mRNA. It is the template strand. A template DNI strand is read in direction 3'→ 5' to build the mRNA molecule that grows in direction 5'→ 3'.During transcription bases forms pairs. RNA replaces Thymine with Uracyl, so pairs are as follows,DNA mRNA
Adenine pairs Uracyl, Thymine pairs Adenine, Guanine pair Cytosine, Cytosine pair Guanine.Translation:
Translation occurs in the cytoplasm. During translation, rRNA reads mRNA in 5' to 3' direction, and tRNA adds the correct amino acid to the growing chain. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.ExampleWe will consider for this example the following DNA template strand.
DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
Transcription
template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
The new mRNA strand is
mRNA ⇒ 3´-AUCUUGCGGAGCUUUAAAGUAUGA- 5´
Once the mRNA synthesis is over, the molecule leaves the nucleus and proceeds with translation in the cytoplasm.

Answer:
precipitation
Explanation:
Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.
Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

How do ecosystems return to normal after a flood?
This really depends on the ecosystem, as each ecosystem may respond differently.
Explanation:
How an ecosystem responds is going to depend on the ecosystem, as each ecosystem may respond differently, and also on the extent and magnitude of the natural disaster. It takes ecosystems a long time to return to semi-normal conditions it can take up to 200 years for a forest to regrow after a huge fire. and that doesn't include the animals displaced/killed in the disaster.

What are the DNA base pairs?
Need asap
Answer:
I hope i helped
Explanation:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins can recognize specific base-pairing patterns that identify particular regulatory regions of genes.

Answer:
A. Individual organisms are able to change their genetic adaptations in
order to better survive in changing environments.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
The statements which are consistent with the concept of natural selection includes;
I. More offspring are produced than can survive in an environment (overproduction of offspring). This ultimately implies that, the more offsprings that are reproduced by the parent organism, the more likely are they to survive.
II. There is genetic variation within populations. This simply means that tere is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.
III. Organisms with beneficial variations are more likely to survive and reproduce, as well as passing on their genes to subsequent generations.

Answer:
Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick
Explanation:
mRNA Vaccines Are New, But Not Unknown
This means the process can be standardized and scaled up, making vaccine development faster than traditional methods of making vaccines. mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV).

Which of the following phrases best describes the function of meiosis?
Group of answer choices
produces genetically unique diploid cells
produces genetically identical haploid cells
produces genetically unique haploid cells
produces genetically identical diploid cells
Answer: C.) Produces genetically unique haploid cells
Explanation: Meiosis will produce genetically unique cells because they are meant to pass onto offspring, and they are haploid because there are half the number of chromosomes in them. The organism will receive 2 sets, one from each parent, so that is why each parent who's cells undergo meiosis have to produce haploid cells.

A geneticist is studying two traits in corn: kernel color and kernel appearance or ‘shine'. The R/r alleles determine kernel color (R – purple color; r – yellow color). The W/w alleles determine kernel ‘shine' (W – waxy; w – dull). The geneticist crosses two corn plants that are Rr Ww and Rr ww . What phenotypic ratio is expected from these two parents?
Answer:
Purple, waxy (R_W_) = 6
Purple, dull (R_ww) = 6
Yellow, waxy (rrW_) = 2
Yellow, dull (rrww) = 2
Phenotypic ratio = 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull)
Explanation:
This question involves two genes coding for kernel color and kernel appearance or ‘shine in corn plants. The alleles for purple kernel (R) and kernel waxy (W) are dominant over the alleles of yellow color (r) and kernel dull (w).
According to this question, a geneticist cross two corn plants that have the genotype: RrWw and Rrww. The following gametes will be produced by each parent:
RrWw - RW, Rw, rW, and rw
Rrww - Rw, Rw, rw, and rw
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Purple, waxy (R_W_) = 6
Purple, dull (R_ww) = 6
Yellow, waxy (rrW_) = 2
Yellow, dull (rrww) = 2
The phenotypic ratio expected from crossing these two parents is 3 (purple, waxy) :3 (purple dull) :1 (yellow waxy) :1 (yellow dull).
