Presentation transcript:

Translation -The main purpose of translation is to create proteins from mRNA -mRNA serves as a template during protein synthesis -this means that, ultimately, only 4 different bases determine the entire genetic make-up of an organism

Translation -mRNA has sequences called codons that consist of three nucleotides -Each codon codes for a single amino acid -there are 20 different amino acids, and but there are 63 combinations of codons -most amino acids have several codon combos

Translation -A start codon signals the beginning of the sequence of codons to be translated, and a stop codon ends the process. (AUG = methionine, start codon)

Translation -Freely floating amino acids within the cytoplasm are bonded to tRNAs that transport the amino acid to the mRNA on the ribosome -As a ribosome moves along the mRNA, each mRNA codon is paired with a tRNA anticodon. Each amino acid is then added to the polypeptide
