Dear aspirant,

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

The term chromosome comes from the Greek words for color (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colorful dyes used in research.

Generally, Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.

Hope this information is helpful to you.

Hello, hope you are doing well!

Chromosomes are genetic material and are a structure of DNA and proteins . It is a single coiled DNA which contains gene on it. These are wrapped around the protein complexes called nucleosomes that consist of proteins called histones.

A DNA is a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Proteins are any class of nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.
