What is the relationship between transcription and translation in the process of gene expression?
A
Transcription converts RNA into DNA, and translation converts DNA into a protein.

Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information in cells from DNA to RNA to protein.
Recognize that transcription is the first step in gene expression, where a specific segment of DNA is copied into RNA, particularly messenger RNA (mRNA), by the enzyme RNA polymerase.
Identify that during transcription, the DNA sequence of a gene is transcribed to produce a complementary RNA strand. This process occurs in the nucleus of eukaryotic cells.
Learn that translation is the second step in gene expression, where the mRNA is used as a template to synthesize proteins. This process occurs in the ribosome, which reads the mRNA sequence in sets of three nucleotides called codons.
Understand that each codon corresponds to a specific amino acid, and transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome, where they are linked together to form a polypeptide chain, eventually folding into a functional protein.
