Chapter 16, Problem 22TYK
Biologists have learned from the technique of “painting chromosomes” with different-colored molecular tags that
- a. the two homologs of a pair of chromosomes differ enough that they stain different colors.
- b. chromosome packing occurs only as the cell prepares for mitosis or meiosis.
- c. heterochromatin is concentrated at the tips and centromeres of chromosomes.
- d. in the interphase nucleus, each chromosome appears to occupy a specific area.

D. Centromeres.
the kinetochore of a metaphase chromosome is
a. The ends of the chromosome that are duplicated by telomerase.
b. The repeated DNA sequence at the centromere that is composed of cohesion protein.
c. A protein complex that assembles on the outer surface of the chromosome to mediate attachment to the kinetochore microtubules
d. The protein complext that contains cohesion and mediates attachment of the sister chromatids.
