BIOLOGY 151 Lecture Notes - Lecture 19: Aminoacyl-Trna, Start Codon, Ribosome
Document Summary
You have discussion next week material in discussion will not be directly relevant to the exam material. Missing discussion section material must be turned in by saturday night. Another assignment due on sunday, october 30th at 11:59pm. Last name begins with a through k thompson 102. Lat name begins with l through z thompson 104. There will be alternative exam review times available through the day of the exam. Synthetase has a recognition site that binds to the anticodons in order to place the correct amino acid onto the trna. If mrna reads 5"aga3", then the trna would carry the amino acid arginine and its anticodon sequence would be 3"ucu5". The ribosome will bind and scan down the mrna until it reaches a start codon. Shifting the reading frame is problematic as it changes the amino acid sequence, and thus changes the protein being produced: genes can have alternative start codons.
