Which account of chromosome structure is correct?
- AA chromosome at the beginning of interphase consists of two identical chromatids, each containing one linear molecule of DNA.
- BTelomeres are lengths of non-coding DNA found at one end of each chromatid to prevent loss of genes during cell division.
- CThe two identical chromatids of a chromosome are held together by a centromere in which there is no DNA.
- DThe very long DNA molecule of each chromatid is coiled and held together by proteins called histones.
