Solution
Transcription
Explanation:
Transcription is the biological process in which the information in a strand of DNA is copied into a new molecule of RNA. During this stage, an enzyme called RNA polymerase binds to a specific gene on the DNA and assembles a complementary RNA strand. Depending on the gene being read, this process can produce mRNA (which carries protein-building instructions), tRNA (which carries amino acids), or rRNA (which forms the structure of ribosomes). While translation involves building proteins from RNA, and transformation involves the uptake of foreign DNA, only transcription is responsible for the actual synthesis of these various RNA classes.
