D
mRNA catalyzes the formation of peptide bonds between amino acids.
Guida verificata passo dopo passo1
Understand the central dogma of molecular biology, which describes the flow of genetic information within a biological system: DNA -> RNA -> Protein.
Identify the role of mRNA in this process. mRNA, or messenger RNA, is synthesized during transcription, where a segment of DNA is used as a template to produce a complementary RNA strand.
Recognize that mRNA carries the genetic information from the DNA in the nucleus to the ribosome, the site of protein synthesis in the cytoplasm.
During translation, the sequence of nucleotides in mRNA is read in sets of three, called codons, each of which specifies a particular amino acid.
Conclude that mRNA serves as a template for protein synthesis during translation, guiding the assembly of amino acids into a polypeptide chain, which will fold into a functional protein.
