Question

chromosomes are made up of a) DNA b) protein c) DNA and protein d) fats

Answer 1

Explanation:

${\mathsf{Chromosomes \:are\:made\:of}}$A) DNA

$\implies$DNA molecules that is Deoxy ribonucleic acid.

$\implies$The DNA is the most stable molecule.

$\implies$A chromosome is basically a strand of DNA in which genes are encoded.

$\implies$ These are tightly coiled many times around the proteins and are known as histones.

$\implies$ These also support its structure.

$\implies$This DNA molecule is packaged inside the nucleus of each cell.

Answer 2

Chromosomes are made up of c) DNA and protein

DNA and proteins combine to form chromosomes.

• Histones are the proteins, and DNA is wrapped around histones.
• Chromosomes are found in the nucleus of every cell. Each cell in the human body contains 23 pairs of chromosomes, each of which contains one chromosome from each parent.
• Non-specific DNA-protein interactions are well understood in structural proteins that bind DNA.
• DNA is retained in chromosomes in interactions with structural proteins.
• The DNA is organized by these proteins into a tight structure known as chromatin.#SPJ6
