Question

what molecule is not going to be used next, after d releases from the strand?

a. dna polymerase iii
b. topoisomerase
c. dna polymerase i
d. rna polymerase
e. primase

Answer 1

To answer the question of which molecule is not going to be used next after DNA releases from the strand, we need to look at the roles of each enzyme mentioned in the context of DNA replication and transcription.

1. **DNA Polymerase III**: This enzyme synthesizes new DNA strands during replication and is actively involved right after the DNA unwinds.

2. **Topoisomerase**: This enzyme helps relieve the tension caused by unwinding the DNA helix, allowing replication to proceed.

3. **DNA Polymerase I**: This enzyme is involved in replacing RNA primers with DNA during replication.

4. **RNA Polymerase**: This enzyme synthesizes RNA during transcription, which is a different process than DNA replication.

5. **Primase**: This enzyme synthesizes RNA primers needed for DNA replication to start.

After DNA synthesis (elongation) is complete and the DNA strands have been separated, DNA polymerase III would not be used again immediately after the DNA has released. Instead, DNA polymerase I would be active next to replace RNA primers, and topoisomerase would continue to help manage the unwinding of the DNA.

Thus, the molecule that is not going to be used next after DNA releases from the strand is:

**d. RNA polymerase**

This enzyme is related to transcription and not directly involved in the next steps of DNA replication following the release of DNA from its strand.
