Chromosomes :

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

structure :

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Types of chromosomes :

There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric.

Function :

Chromosomes facilitate proper cell division and replication. The main function of the chromosome is to fit the DNA inside the nucleus. As we all know, that our DNA is too long, if we unwind all the DNA of a cell, it is up to 2 meters in length.
