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, promoter, 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.
