Question

Eukaryotic chromosomes:

पर्याय

• consist of both DNA and protein.

• may occur as chromatin.

• contain histones responsible for packaging DNA to fit into a small space.

• all of the above.

Answer 1

all of the above.

Explanation:

Eukaryotic chromosomes are highly organised structures that fulfil all the listed criteria to manage large amounts of genetic material. They are composed of a complex known as chromatin, which consists of both DNA and proteins. This organisation involves wrapping the negatively charged DNA around positively charged proteins called histones. These histones act like spools, allowing the massive DNA molecule (which can be about 2 metres long in a human cell) to be condensed into nucleosomes and further coiled into compact fibres that fit into the tiny space of the cell nucleus.
