Question

Part of the chromosome after secondary constriction is called

• A. chromomere
• B. telomere
• C. satellite
• D. primary constriction

Answer 1

The correct option is C satellite

A satellite chromosome or SAT chromosome is one that has a chromosome segment that is separated from the main body of the chromosome by a secondary constriction.

Primary constriction also called centromere is the region of chromosome where the sister chromatids are connected.

Chromomere is a small beadlike structure which can be seen on a chromosome during prophase of meiosis and mitosis.

Telomere is a repetitive sequence of non-coding DNA which is present at the end of chromosome to protect the chromosome from damage.
