Final answer:
Transcription is the process of making mRNA using the sequence of bases in DNA. Its purpose is to produce mRNA that codes for the manufacture of a specific protein.
Step-by-step explanation:
Transcription is the process by which an RNA molecule is synthesized using the sequence of bases in a DNA strand. It involves the creation of messenger RNA (mRNA), which carries the genetic information from the DNA to the ribosomes where proteins are made through translation. The purpose of transcription is to produce a sequence of bases (mRNA) that codes for the manufacture of a specific protein. Each triplet of DNA bases (codon) corresponds to a specific amino acid, and the sequence of codons in the mRNA determines the sequence of amino acids in the protein.
