Final answer:
Transcription is the process of producing an mRNA molecule to deliver the genetic instructions outside the nucleus. It involves the synthesis of mRNA using DNA as a template and is followed by translation to produce a protein.
Step-by-step explanation:
Transcription is the process of producing an mRNA molecule to deliver the genetic instructions outside the nucleus. During transcription, a strand of DNA unwinds and RNA polymerase catalyzes the synthesis of mRNA using the DNA as a template. The mRNA molecule is then modified and sent into the cytoplasm for translation, where it is decoded into a protein with the help of a ribosome.
