A tall pea plant with red flowers has the genotype TtRr. This plant is crossed with another tall pea plant with white flowers, having the genotype Ttrr. What is the probability of getting dwarf plants with red flowers in the F1 progeny

Answers

Answer 1

Answer:

1/8 or 12.5%

Explanation:

This question involves two genes coding for height and flower color in pea plant. The alleles for tallness (T) and red flowers (R) are dominant over the alleles of short (t) and white flowers (r).

According to this question, a tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr). The following gametes is produced by each parent:

TtRr - TR, Tr, tR and tr

Ttrr - Tr, Tr, tr and TR

Using these gametes in a punnet square (see attached image), the following proportion of F1 offsprings will be produced as follows:

Tall, Red (T_R_) = 6

Tall, white (T_rr) = 6

Dwarf, red (ttR_) = 2

Dwarf, white (ttrr) = 2

The probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

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.

The sedimentary rocks exposed throughout the canyon are rich with marine fossils such as crinoids, brachiopods, and sponges with several layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

What are the DNA base pairs?

Need asap

Answers

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.

Thunderstorm cloud have low temperature at the top of the them, ice is formed in the thunderstorm. Thunderstorm clouds are the rain-bearing clouds. Thus, the correct option is C.

What is Thunderstorm cloud?

Thunderstorm clouds are the rain-bearing clouds that also produces lightning. Thunderstorms are dangerous. Every type of thunderstorm produces lightning.

The thunderstorm clouds are menacing looking multi-level clouds, with heights extending up to the sky in towers or plumes. More commonly known as thunderclouds. It is the only cloud type that produces hail, thunder and lightning.

There are three basic ingredients required for the development of thunderstorm, which are moisture, an unstable atmosphere, and some way to start the atmosphere moving. However, the moisture is necessary component to produce the thunderstorm clouds and precipitation.

Therefore, the correct option is C.

i just took the biology learning gizmo five questions

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 synthesis

Proteins 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.

Example

We 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.
