According to the arrangement of the centromere, identify the chromosomes.
According to the arrangement of the centromere, identify the chromosomes.
The correct option is B 1. Metacentric., 2. Submetacentric., 3. Acrocentric., 4. Telocentric.
Metacentric chromosomes have the centromere in the centre, such that both sections are of equal length. Human chromosome 1 and 3 are metacentric.
Submetacentric chromosomes have the centromere slightly offset from the centre leading to a slight asymmetry in the length of the two sections. Human chromosomes 4 through 12 are submetacentric.
Acrocentric chromosomes have a centromere which is severely offset from the centre leading to one very long and one very short section. Human chromosomes 13,15, 21, and 22 are acrocentric.
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.
