A | B | C | D | E | |
(a) | 5 | 1 | 4 | 2 | 3 |
(b) | 5 | 1 | 4 | 3 | 2 |
(c) | 5 | 4 | 1 | 2 | 3 |
(d) | 1 | 4 | 5 | 2 | 3 |
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Identify the components of the diagram, which depicts segments of a gene.
Step 2: The 'Promoter site' (Option A) is responsible for initiating transcription, while the 'Terminator gene' (Option C) marks the end of transcription.
Step 3: The 'Template strand' (Option D) refers to the strand used for RNA synthesis, and the 'Coding strand' (Option E) has the same sequence as the RNA produced, except it has thymine (T) instead of uracil (U).
Step 4: The 'Structural gene' (Option B) refers specifically to segments that encode proteins or functional RNA. Looking at the labeled parts in the diagram, the segments 1, 2, and 3 can be classified under structural genes as they are coding for proteins.
Therefore, Option B is correct.
