Question
Explain the role of RNA in protein synthesis in a cell.
Solution
Protein synthesis takes place in the cytoplasm and for this various types of RNA molecules are involved in it. Protein synthesis is a fast process; and about 20 amino acids are added in one second. During protein synthesis, amino acids are linked together by covalent bonds between the carbonyl groups of one and the amino group of next amino acid. In this way a polypeptide chain is formed; and a protein may be formed of many polypeptide chains.
