A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.

What is the region of DNA where RNA synthesis begins called?

The region of DNA where RNA synthesis begins is the promoter. DNA contains a number of upstream regulatory and promoter sequences but the region of DNA where RNA synthesis begins is the start codon. This is the first codon that translates into an RNA nucleotide.

A mutation in this section of DNA could influence the binding of RNA polymerase to the DNA?

A mutation in the promoter region of DNA, where RNA polymerase binds to initiate transcription, could influence the binding of RNA polymerase. This could alter gene expression by affecting the efficiency or ability of RNA polymerase to initiate transcription of the gene.
