what is called the SAT chromosome?
Answers
Answer:
Satellite chromosomes or SAT-chromosomes are chromosomes that contain secondary constructs that serve as identifying markers. In addition to the centromere, one or more secondary constrictions can be observed in some chromosomes at metaphase. These chromosomes are called satellite chromosomes.
Satellite chromosomes, also known as SAT chromosomes, are chromosomes that contain secondary structures that function as markers. Acrocentric chromosomes are where they can be found. At metaphase, some chromosomes include one or more additional constrictions in addition to the centromere.
A chromosomal satellite is a chromosome region that is divided from the rest of the chromosome by a secondary constriction. As a result, satellite DNAs play an important role in eukaryotic chromosomes, ensuring that all chromosomes are appropriately contained in the interphase nucleus.
