Question

what is meant by chromosomes and explain its types

Answer 1

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). 

Answer 2

Deoxyribonucleic acid (DNA) is the way genetic information is stored within cells and allows the transmission of information from one generation to the next. There are four main types of chromosomes: metacentric, submeta centric, acrocentric, and telocentric. Chromosomes are found within the nucleus of most living cells and consist of DNA that is tightly wound into thread-like structures. Additional protein structures called histones support the DNA molecule within the chromosome.
