What are the two pricipal roles of nucleus? which biomolecule is responsible for these roles?
Answers
Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism's genetic code—the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth. ... Proteins themselves are major structural elements of cells.
Biomolecules are the basic building blocks of living organisms. They have important role in the formation structure and other necessary functions for their survival. The biomolecules are PROTEIN, LIPIDS, NUCLEIC ACID and CARBOHYDRATES.
Explanation:
Nucleus has two major functions
✔️stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism,protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
✔️The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material.
⭐The nucleic acids—DNA and RNA—are the principal informational molecules of the cell. Deoxyribonucleic acid (DNA) has a unique role as the genetic material, which in eukaryotic cells is located in the nucleus. ... In present-day cells, these include reactions involved in both protein synthesis and RNA processing.
