Web11 apr. 2024 · Definition. …. Non-coding DNA corresponds to the portions of an organism’s genome that do not code for amino acids, the building blocks of proteins. Some non-coding DNA sequences are known to serve functional roles, such as in the regulation of gene expression, while other areas of non-coding DNA have no known function. WebThe promoters of eukaryotes and prokaryotes do not have the same conserved sequences. In yeast, the promoter would have the required TATA box located about –30, whereas bacteria would have conserved sequences at –35 and –10 that would interact with sigma factor as part of the RNA polymerase holoenzyme. b.
