WebE) All of the answer options are correct. Which of the following is NOT true of a cDNA clone? A) cDNAs are generally copies of mRNA from expressed genes. B) Reverse … WebTranscription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's transcription. Repressors decrease transcription. Groups of transcription factor binding sites called enhancers and silencers can turn a gene on/off in specific parts of the body.
