Question

Answer the following questions using the given RNA sequence and genetic code found on the last page of this exam. AUGAAAUGCGUGCAGAGCUUUAAUAGAUAG What is the complementary DNA strand to the given RNA strand? How many nucleotides make up a codon? How many codons are in the given RNA strand? What would the forth and seventh anticodon be for the given RNA strand? what type of RNA are anticodons found? What are the sixth and tenth amino acids for the given RNA strand? How many amino acids would be in the protein that resulted from the given RNA strand? What would happen if the ninth nucleotide of the given RNA strand mutated into an "A"? What two things does the first codon code for? How many leucine codons are there in the genetic code?

Explanation / Answer

9. 3' TAC TTT ACG CAC GTC TCG GTG AAA GGC TTA TCT ATC 5'

10. 3 NUCLEOTIDES MAKE UP ONE CODON (TRIPLET CODON)

11. 12 CODONS WITH 1st as start codon and last as stop codon

12. 4th is Valine and anti codon will be CAC and 7th is histidine anticodon is GUG

13. tRNA

14. 6th is serine. 10th is asparagine

15. it ll give a 11amino acid long peptide. (last is non sense/ stop codon)

16. 9th ntd is 'C' part of the 'UGC' codon. Mutation would result in "UGA" codon i.e. stop codon thus, result in premature truncation

17. start codon which is methionine.

18. codons coding for leucine are UUA, UUG, CUU, CUC, CUA, CUG . None are present in the mRNA sequence so, no codon codes for leucine.
