What would be the resulting mRNA sequence from a template strand with this sequence: 5’-CAG CTC GTC-3’? a. 5’-GAC GAG CUG-3’ 5. Which of the following is the correct tRNA anticodon for the mRNA codon 5' GCA 3'? a. 5' UGC 3' 6. If one strand of chromosome 2 has a DNA sequence that consists of this: 5’AAG CGG TAC GTA 3’. What will be the composition of the complementary DNA strand? A) 5’ TTC GCC ATG CAT 3’ B) 5’ TAC GTA CCG CTT 3’ C) 3’ AAG CGG TAC GTA 5’ D) 3’ TTC GCC ATG CAT 5’ a. B and D 7. The following sequence is the coding DNA strand of the collagen gene: 5’ ATG GCG TTC GAA 3’. What is the sequence of the corresponding mRNA? a. 5' AUG GCG UUC GAA 3' 8. During DNA replication, which of the following sequences can be used as a primer for the following DNA sequence: 3' AGT GGA TCA CTA GGC TCT 5'? (Recall that DNA replication uses RNA primers whereas PCR uses DNA primers). a. 5' UCA CCU AGU GAU 3' 9. What is the coding strand sequence if the non-template strand sequence is 5’-AGC CTT TAA CTA3’? a. 3’-ATC AAT TTC CGA-5’ 10. What would the amino acid sequence be from this coding strand sequence: 5’-GGA AGG CCC-3’? a. Gly Arg Pro 11. A mutation in the DNA that changes the sequence of a codon but does NOT change the amino acid sequence of the protein describes a ____________. a. silent mutation 12. A nonsense mutation: a. changes a codon to introduce a premature stop codon 13. Point mutations: a. change a single nucleotide in a mutant gene compared to the normal gene. Examples are missense, nonsense, and silent mutations. 14. A missense mutation:
