Question
Where is the centromere in submetacentric chromosomes?
Open in App
Solution
Centromere
:
Its location on the chromosome varies.
The centromere of metacentric chromosomes is placed halfway between the ends of the chromosome, dividing the two arms.
Submetacentric chromosomes
:
Submetacentric chromosomes are those with centromeres that are visible off-center.
Submetacentric chromosomes have a centromere that is somewhat offset from the chromosome's center, resulting in one short and one long arm.
The centromere in submetacentric chromosomes is
slightly away from its center.
