Final answer:
Transcription is the process where the sequence of DNA bases is transcribed into a complementary sequence of mRNA, which is then used to produce proteins.
Step-by-step explanation:
The process of transcription takes information encoded in a sequence of DNA bases and forms a sequence of mRNA. During transcription, which occurs in the cell nucleus, an enzyme called RNA polymerase reads a strand of DNA and creates a complementary strand of mRNA. This mRNA then carries the genetic code out of the nucleus to ribosomes in the cytoplasm, where translation into protein occurs. Each set of three bases in mRNA, known as a codon, corresponds to one amino acid in the resulting protein.
