WebDec 8, 2024 · Messenger RNA (or mRNA) has the main role in transcription, or the first step in making a protein from a DNA blueprint. The mRNA is made up of nucleotides found in the nucleus that come together to make a complementary sequence to the DNA found there. The enzyme that puts this strand of mRNA together is called RNA polymerase. An anticodon is a unit of three nucleotides corresponding to the three bases of an mRNA codon. Each tRNA has a distinct anticodon triplet sequence that can form 3 complementary base pairs to one or more codons for an amino acid. Some anticodons pair with more than one codon due to wobble base pairing. Frequently, the first nucleotide of the anticodon is one not found on mRNA: inosine, which can hydrogen bond to more than one base in the corresponding codon position. In genetic …
