D)transcription start site;+1

Question

Quizplus · Accepted Answer

The transcription start site is the location in DNA where transcription actually begins, and it is assigned a numerical value of +1. Therefore, base D, "transcription start site;+1," is the correct answer. The promoter is a sequence of DNA that signals the start of transcription and is typically located upstream of the transcription start site. The enhancer is another type of regulatory sequence that can activate or enhance transcription, but it is not typically used to designate specific base locations.
