GENETIC PROBLEMS:

This is the base sequence on one strand of a certain DNA molecule:

3' T A C A A T G C C A G T G G T T C G C A C A T T 5'

1. Give the base sequence on the complementary DNA strand (the other side).

2. Give the base sequence of the strand of mRNA which would be constructed from the original DNA strand.

3. What amino acid sequence would this mRNA code for?

4. If the seventh nucleotide of the original strand of DNA were changed from G to C, what would the resulting mRNA read? Include the entire strand.

5. What would the resulting amino acid sequence be? Include the entire sequence. What type of mutation is this?

6. If a G were added to the original DNA strand after the 6th nucleotide, what would the resulting mRNA read? Include the entire strand.

7. What would the resulting amino acid sequence be? Include the entire sequence. What type of mutation is this?

8. If the 11th nucleotide on the original DNA strand were changed from G to C, what would the resulting mRNA strand read? Include the entire strand.

9. What would be the resulting amino acid sequence? Include the entire sequence. What type of mutation is this?
