Interpretation:
Hit a right click on the image, after that select the ‘Select' option for all proteins. After that, again hit the right click on that image and now select ‘Render' option after this ‘Scheme' and then ‘CPK space fill' option. This results in highlighted ribosomal protein. Now, close the all protein selection tab and now select ‘Nucleic’ then select' ‘CPK space fill' from render

This activity breaks down protein synthesis using the metaphor of PIZZA! Use your
Amino Acids Reference Sheet to complete the following table. Fill in the blank spaces of
each row with either the missing DNA triplet, the mRNA codon, or the Amino Acid.
While there are actually multiple codons that code for any one amino acid, for this
activity there only needs to be one DNA triplet and one corresponding mRNA codon
recorded for each amino acid.
Remember: RNA uses uracil (U) instead of thymine (T)!

To do this, you must follow the procedure of protein synthesis as this is taking place right now in your cells; no short cuts! Practice these steps by following and finishing the partially solved message below. STEP 1: "Build" the mRNA molecule, matching the RNA nucleotides to the DNA nucleotides properly, letter by letter. (For purposes of simplicity, it will be assumed that this mRNA is bacterial; there are no introns to cut out!) STEP 2: Figure out the tRNA triplets (codons) which would fit the mRNA triplets (letter by letter). STEP 3: Look up each tRNA codon in the tRNA Dictionary (below), and find the corresponding symbol and amino acid abbreviation for that codon. Record that one-letter symbol (and its amino acid) below each codon. "Spc" = "space". If you have done this correctly, the…arrow_forwardC.
