Can a gene be changed
WebThere are many different ways that DNA can be changed, resulting in different types of mutation. Here is a quick summary of a few of these: Substitution. A substitution is a mutation that exchanges one base for another (i.e., a change in a single “chemical letter” such as switching an A to a G). Such a substitution could: WebWhat has to happen for a gene to be transcribed? The enzyme RNA polymerase, which makes a new RNA molecule from a DNA template, must attach to the DNA of the gene. It attaches at a spot called the promoter. In bacteria, RNA polymerase attaches right to the DNA of the promoter.
