Respuesta :
The only correct answer would be transcription factors.
The question is a bit tricky: it's asking you for a protein that is essential - so only transcription factors fits this.
Oh, and operators are not genes (they are DNA sequences usually surrounding a promoter sequence)
Promoters are not genes (they are DNA sequences that signal to a mRNA polymerase to start transcription at that point on the DNA)
And structural genes are DNA...not proteins.
Transcription is one of the processes of the central dogma, which involves the making of RNA copies from a genetic sequence.
What proteins are important for regulating gene expression?
- Transcription factors are the proteins that take part in the process of transcribing the DNA into RNA.
- The transcription factors, such as RNA polymerase initiate and regulate the process of transcription of genes. Transcription is the vital and most essential part of gene expression.
Thus, transcription factors are important in the regulation of gene expression.
