Q. No.Although gene expression in eukaryotes can take place at multiple levels. The most common level of gene expression would be:
| 1. | transcriptional level (formation of the primary transcript) |
| 2. | processing level (regulation of splicing) |
| 3. | transport of mRNA from the nucleus to the cytoplasm |
| 4. | translational level |

Identify the correct statements:
| I: | It is the metabolic, physiological, or environmental conditions that regulate the expression of genes. |
| II: | The development and differentiation of embryos into adult organisms are also a result of the coordinated regulation of the expression of several sets of genes. |
| 1. | Only I | 2. | Only II |
| 3. | Both I and II | 4. | Neither I nor II |

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the most appropriate answer from the options given below :
| Assertion (A): | In a transcription unit, the activity of RNA polymerase at a given promoter is in turn regulated by interaction with accessory proteins. |
| Reason (R): | These regulatory proteins can act both positively (activators) and negatively (repressors). |
| 1. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 2. | Both (A) and (R) are false. |
| 3. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 4. | (A) is true but (R) is false. |
