Document Summary
Prokaryotes don"t have introns, no 5" cap or poly-a-tail. No nucleus to separate the two processes for prokaryotes. Figure which ribosome has translated the longest or the least amount of time. Ribosomes are the site of peptide synthesis (ribosomes are essentially the same in both eukaryotes and prokaryotes but they have a slightly different structure, but basically the same) Polarity is on c- or n- end (amino or nitrogenous, carboxyl group) these peptides, like a string of dna have polarity, also has anti-codon. Products which are functional rna products, it is a gene like any other but the bases don"t code for anything, allows for formation of secondary structure. The trna tends to be highly modified (additions or removals of small chemical groups) the modification involves the base inosine (looks like a purine base, double-ring) if this is used it provides trna opportunity to pair with other bases. Can pair with u c or a so there is wobble .
