Which of the following is true for both transcription and DNA replication?
| 1. | The principle of complementarity governs the processes |
| 2. | Only if the two strands act as a template |
| 3. | Only a segment of both strands is involved |
| 4. | Adenine base pairs with thymine |
Consider the following statements:
| I: | All the reference point while defining a transcription unit is made with the coding strand. |
| II: | It is the presence of a promoter in a transcription unit that also defines the template and coding strands. |
| III: | Exons are said to be sequences that do not appear in mature or processed RNA. |
| 1. | I and II only | 2. | I and III only |
| 3. | II and III only | 4. | I, II, and III |
A segment of DNA coding for a polypeptide is most accurately defined as:
| 1. | Operon | 2. | Gene |
| 3. | Recon | 4. | Cistron |
Transcription and translation can be coupled in:
| 1. | Bacteria | 2. | Yeast |
| 3. | Plants | 4. | Animals |
In RNA splicing:
| 1. | Exons are removed and introns are joined together |
| 2. | Introns are removed and exons are joined together |
| 3. | Cistrons are removed and introns are joined together |
| 4. | Introns are removed and Cistrons are joined together |
Identify the correct statement:
| 1. | The coding strand in a transcription unit is copied to an mRNA. |
| 2. | Split gene arrangement is characteristic of prokaryotes. |
| 3. | In capping, methylguanosine triphosphate is added to the 3' end of hnRNA. |
| 4. | RNA polymerase binds with the Rho factor to terminate the process of transcription in bacteria. |
