Statement A : Proteins are polymers of amino acids. Statement B : Nucleic acids are polymers of nucleotides.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Proteins are polymers of amino acids that are joined together by peptide bonds. Whereas, nucleic acids are polymers of individual nucleotide monomers. Between the phosphate and sugar segments of each nucleotide, phosphodiester linkages formed.

Which of the following sequences of mRNA are required for translation process but are not translated?
1 Stop codons
2 Anticodons
3 Sense codons
4 UTR
Explanation:
The sequence of RNA which has a start codon on side and the stop codon on the other and codes for polypeptide is called the translational unit of the mRNA. Some sequences are not translated in the mRNA. They are present before the start codon at the end and after the stop codon at the -end. They are known as untranslated regions (UTRs). However, they aid efficient translation.

How many ATP & GTP molecules are respectively used for each amino acid incorporated in peptide chain?
1 2 & 1
2 1 & 2
3 2 & 2
4 3 & 3
Explanation:
One GTP is hydrolyzed to GDP as each successive amino acid-tRNA complex attaches to the A site of the ribosome. A second GTP is broken down to GDP as the ribosome moves to each new codon in the mRNA. One ATP is hydrolyzed to AMP during amino acid activation. Thus, the formation of each peptide bond uses 3 high-energy molecules, one ATP and two GTP
