What​ is the role of satellite in chromosomes?

Thanks for A2A Sujee Nilux Satellites of chromosomes have repetitive, heterochromatic DNA sequences. During the replication of the chromosomes the ends of chromosomal sequences are truncated. read more

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. In humans, chromosomes number 13, 14, 15, 21 and 22 are examples of SAT chromosomes. read more

The satellite at metaphase appears to be attached to the rest of the body of chromosomes by a thread of chromatin. There are at least 4 SAT chromosomes in each diploid nucleus, and the constriction corresponds to a nucleolar organizer (NOR). read more

Satellite chromosome is actually the terminal segment of a chromosome that is separated from the main body of the chromosome by a secondary constriction. read more
