What is chromosomes and its function?
Chromosomes are the highest level of organisation of DNA and proteins. The main function of chromosomes is to carry the DNA and transfer the genetic information from parents to offspring. Chromosomes play an important role during cell division. They protect the DNA from getting tangled and damaged.

What’s the difference between DNA and chromosomes?
A chromosome is a long chain of DNA molecules that contains part of all of the genetic material of an organism. DNA is a fundamental molecule that carries the genetic instruction of all living organisms. DNA is packed into chromosomes with the help of special proteins called histones.
Do all cells have chromosomes?
Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body.

Sex. The simplest thing DNA can tell you is whether someone is male or female. Apart from some very rare cases, that doesn’t even involve looking at their DNA sequence – all you need to know is whether they have X and Y chromosomes (making them male) or a pair of Xs (which makes them female).
