Question
Match List I with List II:
| List I | List II | ||
|---|---|---|---|
| A. | RNA polymerase III | I. | snRNPs |
| B. | Termination of transcription | II. | Promoter |
| C. | Splicing of Exons | III. | Rho factor |
| D. | TATA box | IV. | SnRNAs, tRNA |
Choose the correct answer from the options given below:
Options
A.A-III, B-IV, C-I, D-II
B.A-IV, B-III, C-I, D-II
C.A-II, B-IV, C-I, D-III
D.A-III, B-II, C-IV, D-I
Solution
Sol. [Key Concept: RNA processing and transcription factors]
The intended matching is A–IV, B–III, C–I, D–II: option (2). RNA polymerase III transcribes tRNA, 5S rRNA and certain small nuclear RNAs. Rho participates in Rho dependent bacterial transcription termination. Spliceosomal snRNPs help remove introns and join exons. A TATA box is a promoter element in many eukaryotic genes.
