DNA is the genetic material composed of about “3 billion” base pairs in the ‘human genome’.
DNA can be imagined as a long thread-like structure which is wrapped around structural proteins known as ‘histones’. Thin is DNA-protein complex is known as chromatin.
The chromatin in turn loops and coils to form more compact structures known as chromosomes. In humans, the thread-like DNA is compacted and organised into “23 pairs of chromosomes” in the nucleus of each cell.
