Question

what is metacentric,sub-metcentric,acrocentric,telocentric


explain in detail!!!​

Answer 1

Chromosomes with centromeres positioned visibly off-center are called submetacentric. Acrocentric and telocentric chromosomes have centromeres positioned very near and at the end of the chromosome, respectively. In the case of telocentrics, the centromere is at the end of the chromosome adjacent to the telomere. IT MAY HELP YOU

Answer 2

Answer:

Metacentric Chromosomes:

Metacentric chromosomes have the centromere in the center, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric.

Submetacentric Chromosomes:

Submetacentric chromosomes have the centromere slightly offset from the center leading to a slight asymmetry in the length of the two sections. Human chromosomes 4

through 12 are submetacentric.

Acrocentric Chromosomes:

Acrocentric chromosomes have a centromere which is severely offset from the center leading to one very long and one very short section. Human chromosomes 13, 15, 21 and 22 are acrocentric.

Telocentric Chromosomes:

Telocentric chromosomes have the centromere at the very end of the chromosome. Humans do not possess telocentric chromosomes but they are found in other species such as mice.
