Ribosomes select the correct trnas
WebbThe ribosome must recognize and align the correct reading frame of the mRNA such that the correct codon sequences can be read. Look at the codon chart in Figure 10.3A. We can see that each codon is specific for a single amino acid. For example UUU is always coding for Phenylalanine and not any other amino acid. Webb12 apr. 2024 · To ensure the correct translation from the nucleic acid code into proteins made of amino acids, cells use RNA adapters, so called transfer RNAs (tRNAs). tRNAs possess an anticodon that pairs with the codons on the mRNA and are aminoacylated at their 3′ end, thereby physically bridging the nucleic acid world with the protein world.
