Question

Give the classification of chromosomes based on the position of the centromere.

Answer 1

Chromosomes :

1. Chromosomes are thread-like structures found within the nucleus of both animal and plant cells.
2. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
3. A chromosome is a lengthy DNA molecule that contains part or all of an organism's genetic material.
4. DNA contains the instructions that distinguish each type of living being.

Classification Of Chromosomes:

Based on the position of the centromere, chromosomes are divided into four categories. Metacentric, sub-metacentric, telocentric, and acrocentric are the four types.

1. Metacentric: A metacentric chromosome is one in which the centromere sits in the center of the chromosome and separates it into two equal arms. During anaphase, they seem V-shaped.

1. Sub-metacentric: A sub-metacentric chromosome's centromere is located distant from the central region. One arm is much longer than the other in this situation. They seem L-shaped during anaphase.

1. Acrocentric: An acrocentric chromosome is one in which the centromere is near to one of the terminal ends. One arm is incredibly long, while the other is incredibly short. They appear J-shaped during anaphase.

1. Telocentric: A telocentric chromosome is one in which the centromere is positioned at one of the terminal ends. They seem I-shaped during anaphase.
