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)! TTG GGG CGT AAA TTT CAA DNA AAC UAU CAC GCA AAA mRNA codon Asparagine Proline Tyrosine Amino Acid Histidine
Check the box under each molecule for which the statement in the first column is true. statement It usually contains several thousand adenine, thymine, cytosine, and guanine residues. It's made in the nucleus, but transported to the cytoplasm to do its job. When combined with a number of different proteins, it forms a large complex in the cytoplasm responsible for synthesizing new proteins. It does not contain instructions for making a protein. There is a specific version of it for every possible amino acid in every possible protein. ribosomal messenger transfer RNA RNA RNA 0 0 0 ☐ 0 X
Consider Molecule X, which is found in all living cells. Each form of this molecule is keyed to the genetic code for a particular amino acid. When activated, the amino acid is covalently bonded to one end of this molecule, and it carries the amino acid to a ribosome to take part in protein assembly. What is the name of X? Your answer should be one word, or a short two- or three-word phrase. Spelling counts. Note: if there is more than one possible answer, separate each answer with a comma. 0
Put the following events involved with protein synthesis in order. Move first event to the top of the list and finishe with the last event. The anticodon of the second tRNA binds at the A site; peptidyl transferase catalyzes a reaction to join the two amino acids together. The stop codon is reached on the mRNA; no tRNA binds, the ribosomes and polypeptide are released. Ribonucleotides are added by RNA polymerase creating a single strand of mRNA. ⠀ The DNA double helix is unwound beginning at the promoter sequence. A 5' cap and 3' poly A tail are added to the mRNA The polypeptide undergoes folding and further modifications, if needed. The ribosome shifts one codon down, opening up its A site. The next tRNA binds. The larger ribosomal unit clamps down on the tRNA carrying MET. The mRNA leaves the nucleus. The 5' cap binds to the small ribosomal unit, leading to the exposure of the start codon; the first tRNA carrying MET binds. :: #10 #

Codon chart: We interpret mRNA 3 base pairs at a time. This is known as a codon. A codon table can be used to translate a genetic code into an amino acid sequence. The full set of relationships between codons and amino acids (or stop signals) is called the genetic code. The genetic code is often summarized in a table like the one below.
