BIO206H5 Lecture Notes - Lecture 10: Start Codon, Radionuclide, Non-Coding Rna
Document Summary
Process that involves the synthesis of a linear sequence of amino acids proteins themselves are made up of a limited number of 20 l-amino acids. Protein synthesis process has a directionality to it very discreet, one step at a time process, one peptide at a time is formed. Protein begins synthesis at n-terminus, guided by the mrna which is translated from the (cid:1009)" e(cid:374)d to the (cid:1007)" e(cid:374)d of rna. Leads synthesis of protein from n-terminus to c-terminus. Once the process is finished, there is post-translational modification. Every organism has protein synthesis machinery 100 different macromolecules that are core requirements for protein synthesis. Three major types of rna that participate: mrna, rrna, trna. Other types of rna molecules such as noncoding rna (snrna involved in spliceosome complex) A single nucleotide coded for a single amino acid would only result in four amino acids not a. 1:1 ratio; similar for a doublet (too small)
