A promoter is a part of a protein that controls the protein’s function. a part of a chromosome that can turn a gene on or off. a part of a mRNA that controls its movement to the cytoplasm. a part of a chromosome that increases DNA replication.

The promoter: A) Is an RNA sequence necessary for activating the transcription of a gene B) Is an RNA sequence necessary for activating translation C) Is a DNA sequence necessary for regulating the transcription of a gene D) Is the site of initiation of gene transcription E) Is a protein factor necessary for activating gene transcription

/ A group of structural genes with a single promoter, operator and terminator, is called A. 'n Regulon / A regulon B. 'n Operon / An operon C. 'n Repressor / A repressor D. 'n Induseerder / An inducerReset Selection

What is the operator? A cis-regulatory DNA sequence in prokaryotes located within or nearby the gene promoter A DNA sequence that regulates the termination of transcription A gene in the bacterial genome only located at the origin of replication A DNA sequence that regulates the transport of DNA out of the bacterial nucleus The site of initiation of translation

Which of the following best describes a promoter?Group of answer choicesA regulatory protein that accelerates mRNA turnoverAn element that promotes termination of transcriptionAn extracellular inducer that controls gene expressionA DNA sequence to which RNA polymerase may bind

What is a transcription factor or transcription regulator? A protein required for mRNA nuclear export A protein that regulates DNA synthesis A protein that interacts with mRNA and increases translation A protein that binds to the DNA origin of replication A protein that binds to a cis-regulatory DNA sequence and affects the probability of gene transcription
