Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Life Sciences Fundamental Processes Protein synthesis and processing
The amino acid Selenocysteine (Sec) is incorporated into polypeptide chain during translation by:
1
charging of Sec into tRNAsec followed by incorporation through serine codon.
2
charging of serine into tRNAsec followed by modification of serine into Selenocysteine and then incorporation through stop codon.
3
charging of Sec into tRNAsec and then incorporation through Selenocysteine codon
4
charging of serine tRNAser with selenocysteine followed by modification of Selenocysteine specific tRNA synthetase and then incorporation through a specially placed stop codon.
