Where does digestion of nucleic acids begin?
Digestion of Nucleic Acids Starts in the Stomach.
What is produced during nucleic acid metabolism?
Nucleic acid metabolism generates and hydrolyzes DNA and RNA molecules and their components in the cell, in the processes of DNA replication, repair, recombination and turnover of DNA, transcription of RNA on DNA, and purine and pyrimidine synthesis and breakdown [1].
How are nucleic acids produced?
The basic component of biological nucleic acids is the nucleotide, each of which contains a pentose sugar (ribose or deoxyribose), a phosphate group, and a nucleobase. Nucleic acids are also generated within the laboratory, through the use of enzymes (DNA and RNA polymerases) and by solid-phase chemical synthesis.
Why nucleic acids are essential for cellular metabolism?
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals.
How nucleotides play role in formation of nucleic acid?
Nucleotides form chains, by binding through ester links established by phosphate between the OH group in C5′ of the pentose of one nucleotide and the OH of C3′ of the pentose from another nucleotide. One extreme of the chain has the 5′ of pentose free and is considered the start of the chain.
Where are nucleic acids synthesized in the cell?
Nucleic Acid Synthesis : Example Question #2 Prokaryotic DNA replication occurs in the cytoplasm, since these cells lack nuclei. Prokaryotic genomes are comprised of a single circular chromosome, with one origin of replication.
How are lipids metabolized?
Lipid metabolism is the process that most of the fat ingested by the body is emulsified into small particles by bile and then the lipase secreted by the pancreas and small intestine hydrolyzes the fatty acids in the fat into free fatty acids and monoglycerides.
