In bacteria, promoters are usually composed ... the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain (Figure 2b).
In addition, regulatory sites on prokaryotic DNA are typically located close to transcription promoter sites ... effectively block RNA polymerase binding (Figure 3). The control of gene ...
RNA is similar to DNA but contains uracil instead of thymine (T) and has a single-stranded structure. Comparison of a ... This process is carried out by the enzyme RNA polymerase, which binds to ...
One type of RNA, called messenger RNA (mRNA), encodes information to make proteins required for the structure and functions ...
RNA polymerase binds to a region just before the gene, called the promoter, before moving down the DNA to the gene. Enhancers are regions of DNA that act as molecular switches for turning genes on ...
