Document Summary
Translation- synthesis of a polypeptide, which occurs under the direction of mrna. During the process, the linear sequence of bases in mrna is translated into the linear sequence of amino acids in a polypeptide. During translation proteins are synthesized according to a genetic message of sequential codons along mrna. Transfer rna (trna)- is an interpreter between the two forms of information- base sequence in mrna and amino acid sequence in polypeptides trna aligns appropriate amino acids to forma a new polypeptide. To perform this action trna must: transfer amino acids from the cytoplasm"s amino acid pool to a ribosome, recognize the correct codons in the mrna. Function: carries amino acids to the ribosome for assembly into polypeptides. Molecules of trna are specific for only one particular amino acid. Anticodon- a nucleotide triple in trna that base pairs with a complementary codon in mrna trnas decode the genetic message, codon by codon.
