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. |
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 |
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. |
