n horses, the hair color gene has a dominant allele B (Black) and a recessive allele b (Chestnut). The gait gene has a dominant
Zinaida [17]

Answer:

The answer is 9.

Explanation:

There are dominant and recessive genes for both the hair color gene and the gait gene in horses, B, b, T and t respectively.

If a black trotter is heterozygous that means it's genotype is going to be Bb and Tt, therefore it will possess both dominant and recessive genes for the two traits.

The allele combinations in the gametes it produces can be BBTT, BBTt, BBtt, BbTT, BbTt, Bbtt, bbTT, bbTt and bbtt .

I hope this answer helps.

The side chain of serine contains oxygen. water-soluble proteins often contain serine. where would the serine side chain most li
bazaltina [42]

Answer;

-On the polar end or the hydrophillic end of the protein.

Explanation;

-Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups.The R group is often referred to as the amino acid side chain.

-Side chains which have various functional groups such as acids, amides, alcohols, and Amines will impart a more polar character to the amino acid. Polar amino acids include serine, threonine, asparagine, glutamine, histidine and tyrosine.

Therefore; serine being a polar or hydrophillic  amino acid will be found on the polar side chain of the protein.

A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut
prohojiy [21]

Answer:

D. The two students who have two fragments have one restriction site in this region.

Explanation:

The DNA samples from the cheek cells were subjected to digestion with a restriction enzyme. This enzyme is an endonuclease and cuts the DNA at a specific sequence only. This sequence is called a restriction site. If the restriction site is not present in the sample DNA, the restriction enzyme cannot cut it. The presence of one restriction site in the sample DNA would cut it into two DNA fragments.

Similarly, the presence of two restriction sites in each DNA molecule would obtain a total of three DNA fragments per DNA molecule.

During transcription , one side of a DNA molecule is used to make a sequence of RNA. What sequence of RNA would be made from the
polet [3.4K]

Answer:

RNA polymerase uses one of the DNA strands (the template strand) as a template to ... and death, because no new RNAs—and thus, no new proteins—can be made. ... During this process, the DNA sequence of a gene is copied into RNA. Before transcription can take place, the DNA double helix must unwind near the gene

Explanation:

i am sorry if this is wrong
