Practice question
Question
Match List I with List II: List I (Enzyme) List II (Activity) A. Reverse transcriptase I. DNA polymerase with no 5'-3' exonuclease activity B. Terminal transferase II. cDNA synthesis C. Klenow fragment III. Addition of poly-A tail at the 3'-end of mRNA D. T4 polynucleotide kinase IV. Addition of a phosphate group at the 5'-end of synthetic oligonucleotide Choose the correct answer from the options given below :
Explanation
The principle of nucleic acid structure and recombination explains that hairpin formation, Holliday junction resolution and translation control ensure fidelity. Hence A-II, B-III, C-I, D-IV fits best because it matches molecular mechanisms of gene expression, as documented in authoritative sources on molecular biology.
