Which among the following is incorrect about chromosomes?a)Chromosomes...
Incorrect statement about chromosomes:
Option C: In acrocentric chromosomes, centromere is present in the end of the chromatids
Explanation:
Chromosomes play a crucial role in the transmission of genetic information from one generation to the next. They are thread-like structures that can be observed during cell division. Let's break down each option and understand why option C is incorrect.
a) Chromosomes are rod-shaped structures that condense together when the cell is about to divide:
- Chromosomes are usually seen as rod-shaped structures during cell division. Before division, the DNA in the cell undergoes a process called condensation, which transforms the loosely packed DNA into tightly coiled structures known as chromosomes.
- This condensation helps in the orderly distribution of genetic material during cell division, ensuring that each daughter cell receives the correct number of chromosomes.
b) Chromosomes are composed of DNA, RNA, and proteins which act as a repository for inheritance:
- This statement is correct. Chromosomes consist of DNA molecules, which carry the genetic information, as well as RNA and proteins.
- DNA is the primary component of chromosomes and contains the instructions for the development and functioning of living organisms.
- RNA molecules play various roles in gene expression and protein synthesis.
- Proteins associated with chromosomes provide structural support and help regulate gene expression.
c) In acrocentric chromosomes, centromere is present at the end of the chromatids:
- This statement is incorrect. In acrocentric chromosomes, the centromere is located very close to one end of the chromosome, but it is not at the end.
- Acrocentric chromosomes have a long arm and a very short arm, with the centromere located near the junction of these arms.
- The centromere is the region of the chromosome where the two sister chromatids are held together.
d) Kinetochores are disc-like structures that are present on the sides of centromeres:
- This statement is incorrect. Kinetochores are protein structures that are present at the centromere region of chromosomes, but they are not disc-like structures.
- Kinetochores play a crucial role in cell division by attaching to spindle fibers and ensuring the proper separation of chromosomes during mitosis and meiosis.
In conclusion, option C is the incorrect statement about chromosomes. Acrocentric chromosomes have the centromere located near the junction of their long and short arms, not at the end of the chromatids.

In conclusion, option C is the incorrect statement about chromosomes. Acrocentric chromosomes have the centromere located near the junction of their long and short arms, not at the end of the chromatids.
