Question

Terms DNA methylation; EVE; Green fluorescent protein; microRNA; plasmid; primers; positive feedback loop; regulatory sequences; RISC; reporter genes; transcription activators; transcription regulators; transcription repressors The transcription of individual genes is switched on and off in cells by transcription regulators. These act by binding to short stretches of DNA called A B inhibit the transcription of genes by blocking the binding of RNA polymerase to the promoter. On the other hand, ( enhance the transcription of genes by promoting the recruitment of RNA polymerase to the promoter. Gene expression patterns that give rise to a differentiated cell must be remembered and passed on to its daughter cells. One important mechanism is (D , in which transcription regulators activate their own genes. Another important process is E of cytosine. This modification of cytosine turns off genes by attracting proteins that block gene expression. G Short noncoding RNA, calledF controls gene expression by forming base-pairing with specific mRNAs, and degrading them.
