The house fly, Musca domestica, has a haploid chromosome number of 6. How many chromatids should be present in a diploid, somati
Vlad [161]

Answer:

12

12

24

Explanation:

<em><u>Musca</u></em> <u><em>domestica</em></u> is the scientific name of an animal popularly known as Housefly.  From the question, it is  known that this organism has a haploid chromosome number of 6.

In a diploid chromosomes, the number of chromatids that will be present will be twice of that in haploid.

Since haploid (n) = 6, diploid (2n) will be; 2 × 6 = 12

Somatic cells on the other hand also exhibit diploid number of chromosomes, again it means we will have (2n) = 2 × 6 = 12

In metaphase cell, cells do make sure they complete the S'phase of the cell cycle before cellular division.Therefore, the DNA present in the chromatids in the S'phase actively engage in chromatids doubling, as a result, 24 chromatids (i.e 12 × 2= 24) exists in the metaphase cell.

Each replication fork requires both leading and lagging strand synthesis. Why?
svet-max [94.6K]

Answer:

Because each strand acts as a template for the synthesis of a new, complementary strand.

Explanation:

This is known as semiconservative DNA replication. Leading and lagging strands are complementary, antiparallel strands (one is 3'-5' while other is 5'-3- direction) which are replicated differently. The leading strand is replicated  continuously while the lagging strand is replicated in fragments-Okazaki fragments. Replication of both strands is performed by DNA polymerase.
