Answer: they are called DNA polymerase and they’re proteins
Explanation:
Heredity.
It helps explain why children tend to resemble their parents, as well as how a genetic disease runs in a family, although some genetic conditions are caused by mutations in a single gene.
Answer:
D) presence of transcription activators or repressors
Explanation:
The reason why this is not post-transcriptional regulation is that activators actually start the process of transcription by binding to specific sites. while on contrary when repressor binds it halt the process.
For example, there is a protein called CAP which in the presence of cAMP bind with promoter region and enhances the activity of RNA polymerase . While in the absence of cAMP it can not bind to promoter hence the transcription stooped.
