Question

An anaphase chromosome contains [DPMT 1991]
A) 1 DNA molecule

B) 3 DNA molecule

C) 2 DNA molecule

D) 4 DNA molecule.explain in detail..

Answer 1

c is the answer for the given question

Answer 2

Answer:

2 DNA also 4DNA molecules.

Explanation:

Since, at the start of the mitosis the number of DNA is 2 times the concentration and the chromosome number is 4 since 2n = 4. So, after completeing the s-phase we will see the DNA concentration increasing to 4C  this concentration will be maintained upto anaphase.

While if we see for meiosis then the DNA will be reduced to 2C at the end of anaphase 2. So. it depends on the type of cycle going in the species.
