Sickle cell anemia is a widespread disease in many African countries and can be caused by a change in the amino acid sequence from glutamic acid to valine. A patient is diagnosed with the disease and a genetic fingerprint reveals the following DNA sequence for the gene: (a) (b) (c) (d) (e) Write down the mRNA sequence for the given DNA sense strand indicating the polarity. Derive the polypeptide from the mRNA molecule using the table of the genetic code (Table Q1 below) again indicating the polarity of the peptide chain. Indicate the position in the DNA molecule that could have caused the disease and write down all possible point mutations in the DNA sequence that could have caused it. [ The polypeptide chain is polymerized at the ribosomes using t-RNA molecules. Write down all possible t-RNA molecules with their anti-codons that are used to polymerize the amino acid VAL. Indicate the polarity. 3'-TAC TGA GCA AGA TTA CAT ACT-5' Explain what is meant by redundancy of the genetic code.…
You are studying a human cancer cell line and you notice that you see the normal amount of RNA but the protein concentration is extremely low. When you investigate more closely you notice that the MRNA is properly processed and in the cytosol but you detect very little protein. When you sequence the mRNA you see no mutations. a) When you sequence the ribosomal RNA associated with the small subunit you notice two transition mutations. What function of the ribosome might be disrupted by these mutations? b) You also sequence the DNA encoding the large ribosomal subunit and notice one substitution mutation. What function of the ribosome might be disrupted by this mutation? c) Suggest one experiment that you might do to determine if the mutations in (a) or the mutation in (b) is the cause of low protein production.

tRNAs a. carry amino acids b. bind to the anticodon present in the mRNA c. adapt the genetic information to the ribosome d. catalyze the peptide bond
The ribosome has 3 tRNA binding binding sites. They are a) EF1, EF2, and EF3 b) 1, 2, and 3 c) A, P, and E
Which of the following is TRUE in translation? A. Amino acyl TRNA containing one amino acid is attached to the P site B. Amino acids/peptides attached to the amino acyl tRNA at the P site are transferred to amino acids at the A site, followed by translocation. C. Empty TRNAS are immediately released from the ribosomes D. The E site is always empty after translocation to receive incoming empty TRNAS. E. The anticodon binding to the codon is stringent, i.e. there must be complete complementary base-pairing between the bases in the codon and anticodon before translation can proceed.
