What is the role of mRNA during protein synthesis?
A
It catalyzes the formation of peptide bonds.
B
It transports amino acids to the ribosome.
C
It carries the genetic code from DNA to the ribosome.
D
It forms the structure of the ribosome.
Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein. This process involves transcription and translation.
Recognize that mRNA (messenger RNA) is synthesized during transcription, where the DNA sequence of a gene is transcribed into a complementary RNA sequence.
Learn that mRNA carries the genetic information from the DNA in the nucleus to the ribosome in the cytoplasm, where protein synthesis occurs.
Identify the role of mRNA in translation, where it serves as a template for the sequence of amino acids in a protein. The ribosome reads the mRNA sequence in sets of three nucleotides called codons.
Understand that each codon on the mRNA corresponds to a specific amino acid, and tRNA (transfer RNA) molecules bring the appropriate amino acids to the ribosome to be added to the growing polypeptide chain.
