What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation?
Homework Answers
Transcriptions factor are the proteins that help the RNA polymerase to bind and initiate the transcription and regulation of other process in transcription. Therefore, they play an important role in regulation of transcriptions or flow of genetic information from DNA to proteins.
As, the first three nucleotide of RNA is not able to transcribe, then amino acid corresponding to that codon will not be translated and it will lead to the formation of immature polypeptide chain or no formation of polypeptide chain, if the start Codon is not AUG.

What is the role of the transcription factors? A mutation exists in transcription factors that causes them to bind slightly downstream of the TATA box, causing them to cover the first 3 nucleotides of a gene. RNA polymerase can still transcribe the gene to mRNA, but it misses the first 3 nucleotides. How would this impact translation? RNA is single stranded, and as such, undergoes rapid rates of mutation. How would this affect the ability of siRNAs to combat RNA...
