In the given diagram, choose the correct options for X, Y, and Z corresponding to the tRNA binding with mRNA.
1
5' Ser 3'
2
5' Tyr 3'
3
5' Tyr 3'
4
5' Ser 3'
Official Solution
Correct Option: (3)
Step 1: Understanding the Diagram. The question involves the translation process, where tRNA binds to the corresponding mRNA. The bases in mRNA are read in triplets (codons), which correspond to amino acids.
Step 2: Analyzing the Options. (A) 5' Ser 3': This option does not match the given diagram based on the codon-anticodon pairing. (B) 5' Tyr 3': This option is close but does not fit the mRNA-tRNA binding shown. (C) 5' Tyr 3': Correct — This is the correct codon-anticodon binding pair. (D) 5' Ser 3': Incorrect, as this does not correspond with the correct codon.
Step 3: Conclusion. The correct answer is (C) 5' Tyr 3', as this corresponds to the correct mRNA-tRNA binding in the diagram.
