Question

For each letter below, write the appropriate name of the chromosome or structure labeled A-D:

11. A)
12.B)
13.C)
14.D)

Answer 1

The appropriate name of the chromosome or structure labeled A-D is as follows:

A - chromosome

B - Centromere

C - chromatid

A chromosome is a linear arrangement of condensed DNA and associated proteins (such as chaperone proteins) which contains the genetic material (genome) of an organism.

A centromere is the central region of a eukaryotic chromosome where the kinetochore is assembled. The two “sister” chromatids are joined at a constricted region of the chromosome called the centromere.

A chromatid is either of the two connected double-helix strands of a metaphase chromosome that separate during mitosis.
