translation, process of synthesizing specific polypeptide on a ribosome using the mRNA template, where is DNA Found?, in the nucleus , where is protein synthesis?, takes place in the cytoplasm, Transcription, produces a transcript (RNA copy) of a gene this message RNA (mRNA) specifies the amino acid sequence of a polypeptide, terminator, signals the end of transcription, genotype , changes in the gene, phenotype , physical changes that you can see, gene expression , process of translating the information in DNA into function molecule within the cell, three stages of transcription are what, Initiation, elongation, and termination, prompter, a sequence of DNA needed to turn on a gene on or off., RNA polymerase, is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, Activator, A DNA-binding protein that positively regulates the expression of one or more genes; that is, transcription rates increase when an activator is bound to the DNA. (2) A positive modulator of an allosteric enzyme., Repressors, The protein that binds to the regulatory sequence or operator for a gene, blocking its transcription., Coactivators, A protein that stimulates transcription by binding both the RNA polymerase and an activator or activators, without binding the DNA directly. Compare corepressor and DNA-binding transcription activator, Transcription factors, In eukaryotes, a protein that affects the regulation and transcription initiation of a gene by binding to a regulatory sequence near or within the gene and interacting with RNA polymerase and/or other transcription factors..
