WebNitrogenous bases are one of the three groups that make up a nucleotide (along with a pentose sugar and a phosphate group) and do not need to be added on during transcription (nucleotides do). Ribosomes do not add nucleotides to the growing mRNA molecule, RNA polymerase does. WebIn bacteria, genes are often found in operons In bacteria, related genes are often found in a cluster on the chromosome, where they are transcribed from one promoter (RNA polymerase binding site) as a single unit. Such a cluster of genes under control of a single promoter is known as an operon.
