c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules
d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.
e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.
