Question

Brief the pathway involved when a particular protein is required.

Answer 1

Protein synthesis:

1. Proteins are macromolecules that perform various functions in the body.
2. When a particular protein is required in the cell, the nucleotide sequence is copied from one strand of the DNA into mRNA.
3. This process is known as transcription.
4. Messenger RNA or mRNA contains nucleotide sequences that are arranged in codons that code for specific amino acids.
5. During translation, the codons present in the mRNA are translated into a polypeptide.
6. A polypeptide is a chain of amino acids that are bound together with peptide bonds. The polypeptide serves as a functional protein in the cell.
