Why are AT pairs are easier to pull apart than GC pairs during the unwinding process

1 answer:

5 0

Initiator proteins break hydrogen bonds separating short length of DNA, AT base pairs are held together by fewer hydrogen bonds than GC pair. Thus AT pairs are easier to pull apart, At rich regions are typically found in the replication origins. Replication origins are site at which DNA is first opened.

Micah has straight hair. If he is homozygous for the gene that determines straight hair, what is true of his parents?

alexgriva [62]

Answer:

They have contributed same allele for straight hair.

Explanation:

There are two conditions homozygous and heterozygous. In homozygous conditions both the allele of a particular gene is same in an offspring which means the offspring got two same alleles from its parent for a particular gene and if an offspring is heterozygous for a gene that suggests that the parent has contributed two different alleles for that gene in the offspring.

So If Micah is homozygous for straight hair then it can be concluded that his parents have contributed two same alleles for straight hair genes.

6. negative

Explanation:

In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.

If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.

f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix
