Two sister chromatids are joined at the centromere prior to meiosis. Which statement is correct? a. These chromatids make up a d
iploid chromosome. b. Barring mutation, the two sister chromatids must be identical. c. The cell that contains these sister chromatids must be haploid.
b. Barring mutation, the two sister chromatids must be identical.
Explanation:
Prior to meiosis, the DNA is replicated so cells enter division with all its chromosomes having two sister chromatids united at the centromere.
DNA replication is semiconservative: the original DNA strands are separated and new strands are synthesized using the original ones as templates. As a result, each sister chromatid is made of one original DNA strand and a newly synthesized DNA strand, and both should be identical to each other.
