The chromosomes in which the centromere is situated close to one end are:
Acrocentric
Telocentric
Sub-metacentric
Metacentric
The Nucleus -
The Nucleus
The nucleus is the most prominent and important membrane bound organelle of the eukaryotic cell.
It is referred to as the brain of the cell because it contains the DNA which is responsible for carrying the information of various functions of the cell.
It was discovered by Robert Brown in 1831.
Based on the position of the centromere, the chromosomes can be classified into four types:
1) Metacentric chromosome- middle centromere forming two equal arms.
2) Sub-metacentric- centromere slightly away from the centre.
3)Acrocentric- centromere is situated close to its end
4)Telocentric- terminal centromere
Acrocentric chromosomes - centromere is situated close to its end
