Question

PLS, HOW DOES A RNA POLYMERASE KNOW WHAT DNA STRAND TO USE AS A GENE TEMPLATE IN THE TRANSCRIPTION UNIT DURING TRANSCRIPTION?

Answer 1

Only one strand of DNA is active during the transcription process. A promoter is a part of a DNA that starts the transcription of a particular gene. It is double-stranded, directional, and specific. The promoter itself is not transcribed but instead it aids in the process.
