Question

As part of the transcriptional unit, regulatory sequences are the sites where RNA polymerase and transcription factors bind to regulate transcription.

Answer 1

Regulatory sequences in the transcriptional unit are the sites where RNA polymerase and transcription factors bind to regulate transcription. Transcription factors can be either activators or repressors, promoting or preventing transcription, respectively.

Step-by-step explanation:

The regulatory sequences, also known as regulatory elements, are the sites in the transcriptional unit where RNA polymerase and transcription factors bind to regulate transcription. These sequences are usually located near the promoter region of a gene and play a crucial role in controlling when and how much mRNA is produced. The regulatory proteins, known as transcription factors, can be either activators or repressors, enhancing or preventing transcription, respectively.
