Question

What do the structures inside a Nucleus do?

Answer 1

*Storage of hereditary material, the genes in the form of long and thin DNA (deoxyribonucleic acid) strands, referred to as chromatin.
*Storage of proteins and RNA (ribonucleic acid) in the nucleolus.
*Nucleus is a site for transcription in which messenger RNA (mRNA) are produced for protein synthesis.
*Exchange of hereditary molecules (DNA and RNA) between the nucleus and the rest of the cell.
*During the cell division, chromatins are arranged into chromosomes in the nucleus.
Production of ribosomes (protein factories) in the nucleolus.
