Termination Once a gene is transcribed, the bacterial polymerase must dissociate from the DNA template and liberate the newly made RNA.
WebFor example, adenine (A) is always paired with thymine (T), and cytosine (C) is always paired with guanine (G). This is because hydrogen bonds hold the nitrogen atoms together. This arrangement helps keep the DNA molecule stable and intact and makes sure that genetic information is stored and passed on correctly. 9) ATCCAG.
