BI110 Lecture Notes - Lecture 11: Cistron, Base Pair, Start Codon
Document Summary
Aminoacyl trna synthases (stick amino acids on trna) trna. Large holds the different sites mrna goes in between the small subunit. *ribosomes in humans & bacteria are slightly different - this is how antibioti work (they stick to bacterial ribosomes & stops translation, therefore prote cannot be formed) A codon is each group of three adjacent nucleotides coding for a s tics teins single. A codon is each group of three adjacent nucleotides coding for a s aa. The reading frame is where the ribosome begins reading the seque nucleotides trna. The resulting structure looks like a cloverleaf when drawn flat. This shows the base pairs well, but not biologically correct. No pairs in the loops (anticodon loop, dhu loop, etc) The 3" hydroxyl of the a is the attachment site for the aa single ence of. Anticodon = sequence of 3 nucleic acid bases which will pair with 3 b mrna.
