According to the central dogma of molecular biology, genetic information is transferred from DNA to RNA to protein.
Which of the following is true regarding the transcription of DNA into mRNA?
- RNA polymerase synthesizes mRNA in the 5' rightarrow 3' direction using the template strand.
- Transcription occurs solely in the cytoplasm for eukaryotic cells.
- The sequence of the mRNA is identical to the template strand (with U replacing T).
- RNA polymerase requires a short RNA primer to begin synthesis.
