Genetic Mutations
Use the genetic sequence below to answer the following questions:
TAC CAT GCT GCG AAA CTT TGG ATC
1. What is a start codon? What is its sequence?
2. What amino acid does the start codon code for?
3. Transcribe the DNA sequence below. Where does transcription take place in a cell?
4. Translate the DNA sequence below. Where does translation take place in a cell?
5. If the sequence was re-written like this: TAC CAT GAT GCG AAA CTT TGG ATC. What is the new
amino acid sequence?
6. How does the sequence differ from the original?
7. What type of mutation caused this change?
8. If the sequence was re-written like this: TAC CAT GCT GCG AAC TTT GGA TC. What is the new
amino acid sequence?
9. How does this sequence differ from the original?
10. What type of mutation caused this change?
