On condensation, __________ forms chromosomes:
On condensation, __________ forms chromosomes:
The correct option is: A
Explanation of the correct option:
A network of thin long fibres observed in the nucleus, when it is at rest or in an undivided stage, is called chromatin fibres. They are made up of DNA. As the cell enters division, the chromatin fibres condense to form structures called chromosomes.
Explanation of the incorrect option:
Option B: Centromeres help in the proper alignment and segregation of the chromosomes during the process of cell division in eukaryotic cells.
Option C: The centromeres are the point of attachment of the kinetochore. The main functions include the attachment of sister chromatids, and it is the site for the attachment of spindle fibre.
Final answer: On condensation, Chromatic fibres form chromosomes.
