Question

The round worm Ascaris megalocephala have a diploid complement of 4 chromosomes. For each of the following stages of the cell cycle, state the number of chromosomes, the number of sister chromatids, the number of DNA strands, and the DNA (or genome) content (as the factor of c) and ploidy (halploid (n) or diploid (2n)).

Answer 1

Answer:

Let's add the missing piece of information

The stages of the cell cycle in question are

G1 (mitosis)

G2 (mitosis)

Anaphase of mitosis

Anaphase I of meiosis

Late telophase I meiosis/nucleus

Late telophase II meiosis/nucleus

We know from the question that

The round worm Ascaris megalocephala have a diploid complement of 4 chromosomes.

So, we put our answer (which is the attached image) in a tabular form to indicate the number of chromosomes, the number of sister chromatids, the number of DNA strands, and the DNA (or genome) content (as the factor of c) and ploidy (halploid (n) or diploid (2n)) for each stage of the cell cycle

Note,

* the division of the centromere results in chromosomes production from the sister chromatids.

**It indicates the individual DNA strands
