Document Summary

Bio 111 lecture 6 genes and the genetic code, darwinian evolution. *reminder: exam friday @ 8:30am in lower strong. Introns: sections removed from pre-mrna during processing: extrons: parts of coding region sent to cytoplasm to be translated. *any of these parts of a gene can have a mutation that effects how the gene is expressed. Most regulation regarding protein formation occurs during transcription: each made up of 3 ribosomal rnas and approx. Genetic code the rules that indicate what codon translates to which amino acid; translates nucleic acids into proteins fu(cid:374)da(cid:373)e(cid:374)tal to (cid:862)all life ca(cid:373)e from the sa(cid:373)e place(cid:863) theory because this code holds true for nearly every organism https://byjus. com/biology/genetic-code/ Steps of translation: bind the mrna, ribosomes bind the charged trna. Charged trna: trna that is covalently bonded to amino acid, this process requires atp. Each trna is associated with a specific amino acid determined by trna synthase.
