What is the purpose of replication?
Greeley [361]

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

Labrador retrievers' fur color is controlled by two alleles, E and B. Any dog with the ee_ genotype d evelops into a yellow lab,
Talja [164]

This is an example of <u>recessive epistasis</u>.

Here the presence of recessive allele ee at one locus inhibits the phenotypic effect of genes at the B locus.

As it is mentioned in the question above the ee__ genotype develops into a yellow lab.  

Dominant B gene can produce the black coat color phenotype only when a dominant allele E is also present.

If the genotype is B_ee, then yellow coat color would be produced.  

Therefore the recessive allele e  in homozygous ee form masks the effect of the dominant  B allele.

Recessive epistasis is the phenomenon in which the expression of one gene pair is depending on some other gene pair. In different words, one gene must be grown to become one for any other gene to be expressed.

The annealing temperature varies greatly between different PCRs. Explain why this is so.
Vika [28.1K]

Answer:

The process of annealing temperature varies greatly with the different PCRs this is because the type of primer is specific to the temperature.

Different set of primers have different temperature by which the DNA binds. The temperature 42°C  was used on  the primers like T11CG, T11GG,T11GC and T1CC and there was less complimentary fragments.

When the temperature was taken 40°C showed 2 mole folds and better complementary fragments was seen.

This concludes that annealing temperature varies with Different PCRs.
