Homework Answers
Aminoacid attachment site and anticodons are structural components of tRNA . Overall function of tRNA is transfer of aminoacids during protein synthesis .
Amino acid attachment site at 3' terminus carries aminoacids to the mRNA during protein synthesis. Aminoacid is attached to this site by forming covalent bonds that is aminoacyl bond . The enzyme which helps in attachment of aminoacids to the site is aminoacyl tRNA synthetase . This process is called aminoacylation .
Anticodons are complimentary codons for mRNA , which are present in tRNA . The charged tRNA get attached to the mRNA through this site ,so that elongation of polypeptide chains can occur . A tRNA contains one anticodon at the head region and one amino acid attachment site at the tail region . Both these sites are essential for translation process that is protein synthesis.

Draw an. ionized version of an amino acid and label the major parts(N terminus, C-terminus, alpha-carbon, backbone) of the molecule. Specifically describe how an amino acid is affected by different pH’s (<7, 7, >7). Which form is most common and why/how is that important for cell function/survivability?

Site-directed mutagenesis replaces a specific amino acid in a protein with a different amino acid, and this approach is commonly used by biochemists to determine if an amino acid is essential for a protein’s function and probe that residue’s role in that function. Which of each pair of amino acid substitutions listed below would you expect to disrupt protein structure the most? Explain. a. Gln replaced by Glu or Asn b. Lys replaced with Asp or Arg c. Thr replaced...

When amino acid monomers are joined together, they are always arranged so that the 'C-terminus' of one amino acid is covalently bonded to the 'N-terminus' of the other. How would this 'polymerization' occur chemically? Draw your answer on a paper using the figure below and indicate what this chemical process is called: Upload the picture of the file.
