Document Summary
An mrna sequence is decoded in sets of three nucleotides the conversion of rna into protein represents a translation translation into the amino acid sequence of a protein is done through the genetic code. In principle, an rna sequence can be translated in any one of three reading frames, depending on where the decoding process begins trna molecules match amino acids to codons in mrna. The translation of mrna into protein depends on adaptor molecules that recognize and bind to both the codon and the amino acid: these adaptors are called trna (transfer. Rnas); roughly 80 nucleotides in length trna folds into a cloverleaf-like shape. Two regions of unpaired nucleotides situated at either end of the l-shaped molecule are crucial to the function of trna in protein synthesis. One of these regions forms the anticodon , a set of 3 consecutive nucleotides that pair with the complementary mrna codon.
