Solution
The enzyme that builds RNA from a DNA template is RNA polymerase. This enzyme plays a critical role in the process of transcription, where the information encoded in DNA is transferred to RNA. During transcription, RNA polymerase binds to a specific region of the DNA (promoter) and synthesizes a single strand of RNA complementary to the DNA template strand. This process is essential for protein synthesis and gene regulation in cells.
Here's a brief overview of the other options:
- DNA polymerase: Synthesizes DNA from a DNA template during replication.
- Ligase: Joins together DNA fragments by forming covalent bonds.
- RNA primase: Synthesizes short RNA primers needed for DNA replication.
- Gyrase: Relieves the strain of unwinding DNA ahead of the replication fork.
In summary, for building RNA, the correct choice is RNA polymerase.
