1. Translation is the biological polymerization of amino acids into polypeptide chains from MRNA. 2. Transfer RNA adapts specific codons in mRNA to their correct amino acids by hydrogen bonding with MRNA to hold amino acid in proximity so peptide bond can form. 3. In tRNAS, 3-methylcytidine is a modified base of guanosine (G).

True or False

BIOINFORMATICS 11. Aminoacyl-tRNA synthetases catalyzes formation of the peptide bonds joining adjacent amino acids. 12. Using Sanger sequencing researchers have recently gained a remarkably detailed view of the complicated structure of the ribosome. 13. FRNA acts as a ribozyme that joins amino acids together. 14. Formylmethionine (IMet) recognize the initiation codon. 15. In prokaryotes, special signal sites such as ribosome binding site, has three significant elements. 16. The initiator tRNA in eukaryotes carries modified fMet instead of Methionine. 17.A complex of several ribosomes translating from the same mRNA is called a polypeptide chain. 18. When movement of the ribosome brings a nonsense codon into the ribosome's A site, no tRNAs can bind to that codon. 19. The elongation machinery adds amino acids to the C terminus of the lengthening polypeptide, polypeptide synthesis proceeds from the N terminus to the C terminus. 20. Posttranslational changes to a protein can be very important: ie, the biochemical function of many enzymes directly depends on the addition (or sometimes removal) of nucleotide groups.

Transiation Read each statement below carefully. Shade an "A on your answer sheet if you think the statement is TRUE Shade a "B on your answer sheet if you think the statement is FALSE 1. Transiation is the biological polymerization of amino acids into polypeptide chains from MRNA. 2. Transfer RNA adapts specific codons in MRNA to their correct amino acids by hydrogen bonding with MRNA to hold amino acid in proximity so peptide bond can form. 3. In IRNAS, 3-methylcytidine is a modified base of guanosine (G). 4. Cloverleaf shape; this is the tRNA's tertiary structure. 5. The anticodon forms base pairs with other regions of the RNA; i is always available for base pairing with its complementary mRNA codon. 6. Aminoacyl-tRNA synthetases are the only molecules that read the languages of both nucleic acid and protein. 7. A IRNA covalently coupled to its amino acid is called an uncharged tRNA. 8. The flexibility in base pairing between the 3' nucleotide in the codon and the 5 9. In E. coli, ribosomes consist of 5 different ribosomal RNAS (FRNAS) and 52 different ribosomal proteins. 10. Eukaryotic ribosomes have more components than their prokaryotic counterparts.
