Document Summary

Study sessions: biomes active learning group: monday, jan 23 3:30-5:00 28lsb, tus jan 24 7:00-8:30, base pairing: makes the rna strand fold on itself , the anti codon binds to its complimentary base pairs on the. Initiation complex: a trna with an attached methionine amino acid binds to a small ribosome unit. Large risosomal subunit: is a strand of rna. The genetic code table decides what thing will code for. The codons: after the two codons are next to each other a chemical reaction from the energy atp forms a peptide bond, it is catalyze by an enzyme called the large ribosomal subunit. Translation: elongation: frame- the three nucleotides that makes up one codon, frame shift mutation: you can do an insertion to change the codons, Mutation: any change in the sequence of bases in dna, 3 types, point mutation, deletion mutation insertion mutation both frame shift mutations.
