Question

Part of chromosome after secondary constriction is called as

• A. Chromomere
• B. Telomere
• C. Satellite
• D. Nucleolar organiser

Answer 1

The correct option is C Satellite

Chromosomes are the carrier of genetic information in form of DNA. The secondary constrictions are used as a point of identification of chromosomes. These are always constant in their positions and hence, can be used as markers that identify particular chromosomes. A satellite chromosome or SAT chromosome has a chromosome segment that is separated from the main body of the chromosome by such a secondary constriction.

So, the correct answer is option C.
