Question

For a prokaryotic gene, basal transcription is defined as

Answer 1

Answer:

Option B, Transcription that originates at the core promoter and +1 site

Explanation:

In basal transcription  process a special class of transcription factors which  are nothing but the protein that binds to specific sites  on DNA (which are also known as promoter sites) with an objective of activating transcription of genetic information from DNA to RNA , specifically messenger RNA. The transcription initiation requires association at promoter site(or regions of DNA that are found in the upstream of the coding region of  a gene)  along with a  σ sub unit

Hence, option B is correct
