Summary Introduction
To review:
The role of introns and exons.
Introduction:
The genetic material of a cell comprises DNA (deoxyribonucleic acid), which is packed inside the nucleus in the form of chromatin. It contains genes that code for all the information about the organism. These genes are transcribed into mRNA (messenger ribonucleic acid), which is further processed and translated into the corresponding protein.
