Question

Class 13 Translation DTL 1. Draw a line representing mRNA that has already been processes (introns removed, cap and tail added). Label the 5' cap on left end and polyA tail. 2. An inch from the left add the start codon (AUG). 3. An inch from the right add one of the three stop codons. 4. Label the 5'UTR and 3 UTR (untranslated regions). 5. In the middle of your mRNA, draw two ovals representing the large and small subunits of the ribosome bound to the mRNA. Make these large enough that you can add the details below. In between the two subunits indicate the ribosomal A, Pand E sites in the correct place. Put an arrow on top of ribosome to show direct of translation 6. Draw at least 3 tRNA on your picture in the correct locations: an empty one (no amino acid) exiting the ribosome, a charged tRNA with a small circle on the 3' end to indicate an amino acid, and a tRNA with several small circle representing amino acids in a chain (polypeptide). 7. Indicate the amino end of polypeptide with an "N". (Remember each amino acid has polarity but they don't have 5' and 3 carbons, they have amino and carboxylic acid ends.)
