DNA transcription is the process of copying a section of DNA into RNA. This is done by enzymes called RNA polymerases, which move along the DNA and create a complementary RNA strand. Transcription is an important part of gene expression, as it allows a gene’s information to be used to create proteins. Introduction to DNA…

DNA is a molecule that contains the genetic instructions used in the development and function of all known living organisms and many viruses. These instructions are stored as a code made up of four chemical bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The code specifies the sequence of the building blocks, called…
