Question

Which of the following is the best definition of chromosome?

Answer 1

The answer is either a or c

Answer 2

Answer:

The correct answer will be option C.

Explanation:

Chromosome is a packaged structure of DNA observed in the cell nucleus during metaphase stage of cell division when aligned in the equatorial plate of the cell.

Chromosomes number varies in different species which facilitates replication and distribution of the DNA to new daughter cells during cell division.

Chromosome is formed after coiling of DNA many times around proteins called histones which provides the structural support to DNA and form a special structure nucleosomes,  further coil up and create chromatin loops which further coil around each other and make a full chromosome.  

Thus, option C is the correct answer.
