What is the purpose of a chromosome centromere?
A)Connecting sister chromatids to form a chromosome
B)Preventing the chromosome arm tips from unraveling
C)Allowing chromatids to separate during DNA replication
D)Ensuring that DNA replication proceeds only in the 3'-to-5' direction

Question

Quizplus · Accepted Answer

A centromere is the pinched-in area of the chromosome that connects the two halves (sister chromatids) together in a metaphase chromosome. It also connects the chromosome segments above it and below it. The centromere has no role in DNA replication. The telomeres prevent chromosome unraveling. DNA replication proceeds in the 5'-to-3' direction and is determined by specific enzymes, not the centromere.
