WebThe Latin prefix cis means "on this side", i.e. on the same molecule of DNA as the gene(s) to be transcribed. CRMs are stretches of DNA , usually 100–1000 DNA base pairs in length, [1] where a number of transcription factors can bind and regulate expression of nearby genes and regulate their transcription rates. WebGenes can be transcribed into mRNA with different efficiencies. b. Many ribosomes can bind to a single mRNA molecule. c. Proteins can be tagged with ubiquitin, marking them for degradation. d.
