Consider the following statements:
| I: | Inheritance of a character is affected by the promoter and regulatory sequences of a structural gene. |
| II: | The split-gene arrangement represents an ancient feature of the genome. |
| III: | The process of splicing represents the dominance of the RNA world. |
Which of the above statements are true?
| 1. | I and II only |
| 2. | I and III only |
| 3. | II and III only |
| 4. | I, II, and III |
| 1. | 3' (downstream) end and 5' (upstream) end, respectively, of the transcription unit |
| 2. | 5' (upstream) end and 3' (downstream) end, respectively, of the transcription unit |
| 3. | the 5' (upstream) end |
| 4. | the 3' (downstream) end |
| Assertion(A): | The non-template strand of DNA is called the coding strand. |
| Reason(R): | This is the strand that is used by convention when presenting a DNA sequence. |
| 1. | Both (A) and (R) are True and (R) correctly explains (A) |
| 2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
| 3. | (A) is True, (R) is False |
| 4. | (A) is False, (R) is False |
| Assertion (A): | RNA polymerase binds to the promoter region to initiate transcription |
| Reason (R): | The promoter region is located downstream with respect to the structural gene in a transcription unit. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A) |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
