Question

Discuss briefly the role of nucleolus in the cells actively involved in protein
synthesis.


NCERT Class XI
Biology - Exemplar Problems

Chapter 8. The Unit of Life

Answer 1

The nucleolus disappear during cell division and reappear at the end of it. This is how, it helps in protein synthesis.

Answer 2

HLO MATE HERE IS UR ANSWER.

• Spherical body present in the nucleoplasm is called nucleouls.
• It is not a membrane bounded structure.In some nucleus, one or more nucleoli may be present.
• Nucleolus actively synthesizes ribosomal RNA(rRNA).
• rRNA synthesizea proteins.
• several ribosomes attach with a mRNA (Meaasenger RNA ) to form a chain are reffered to as a polyribosome or polysome.
• The ribosomes of a polysome translate the mRNA into proteins.
• Larger and more numerous nucleoli present in cells actively carryout protein synthesis.
