How many types of bacterial rna polymerase
Web11 jul. 2015 · Summary RNA exists in several different single-stranded structures, most of which are directly or indirectly involved in protein synthesis or its regulation. The linear array of nucleotides in RNA consists of A, G, C, and U, and the sugar is ribose. All types of RNA has a 5’ and 3’ terminal. m-RNA is in linear form, hetrogenous in size and is immediately … WebSpecifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand. Stages of transcription Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria.
