Question

function and deffinition of nucleas

Answer 1

A dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.

Nucleus functions:-

• It is responsible for protein synthesis, cell division, growth and differentiation.
• Stores heredity material in the form of deoxy-ribonucleic acid (DNA) strands.Also stores proteins and ribonucleic acid (RNA) in the nucleolus.
• It is a site for transcription process in which messenger RNA (m RNA) are produced for protein synthesis.
• Aids in exchange of DNA and RNA (heredity materials) between the nucleus and the rest of the cell.
• Nucleolus produces ribosomes and are known as protein factories.
• It also regulates the integrity of genes and gene expression.
