Question

SAT chromosome has

• A. More heterochromatin part.
• B. More G $\equiv$ C part.
• C. More non histone protein.
• D. More amount of lipid.

Answer 1

The correct option is A More heterochromatin part.

SAT chromosome has more heterochromatin part. 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. The satellite at metaphase appears to be attached to the rest of the body of chromosomes by a thread of chromatin. If the secondary constriction contains the nucleolus organizer region, the chromosome is called a nucleolar satellite chromosome.There are at least 2 SAT chromosomes in each diploid nucleus. They play a vital role in the formation of the nucleolus after cell division is completed.
