Document Summary
Sense strand + antisense strand (template) ; dna replication. Exons/codons + introns ; make up a transcription unit. Start (often methionine - aug) + stop codons mrna cap at 5" end, polya tail at 3" end. Ribosome moves along mrna reading codons and adding amino acids from trna w anticodons. Amino acids join by a peptide bond (deposited by atp) A" site (to the right of p site trna attachces). E site = exit site for trna of the ribsosome. R = ph, charge, polar or non-polar of amino acid (created a diff type of protein). Genome made up of exons + related sequences (pseudogenes, gene fragments, intron, promoter regions) + no obvious role genes (research currently on this). Gene regulation enhancer (activates expression of multiple different genes. Attract proteins whether gene is turned on or off/needed to be used at the time), regulate if a gene is transcribed or not.
