Mutation Problems

1

Create a complementary strand to the following DNA strand:
Parent strand - TAC AAA TAT CGG TTT CCG CAA TCG ATA AGG GGG GCA For the gene we are studying here, this original parent strand will be considered the template strand.

1

What type of strand did you just create? (hint - this is a vocab word)

1

Transcribe the template strand from above to create the mRNA.

1

Translate the mRNA in your answer above into a protein sequence. (you may use the abbreviation for each AA )

For Questions #3 - 7

Suppose the bases in the DNA above (TAC AAA TAT CGG TTT CCG CAA TCG ATA AGG GGG GCA) were not transcribed correctly and the mRNA now read:

AUG UUU AUA GCC AAG GGC GUU AGC UAU UCC CCC CGU

1

Compare this new mRNA to the normal mRNA in question #1. How many mistakes were made during transcription?

1

Translate the mRNA above into a protein sequence. (spell each amino acid correctly and put a dash and no spaces between each).

1

Were any amino acids changed due to any mistakes? If so, which ones?

1

What type of mutation is this? Choose the best answer

For Questions #8 - 12

Suppose the bases in the DNA above (TAC AAA TAT CGG TTT CCG CAA TCG ATA AGG GGG GCA) were not transcribed correctly and the mRNA now read:

AUG UUU AUA GCC AAA GGC GUA GCU AUU CCC CCC GU

1

Translate the mRNA above into a protein sequence. (spell each amino acid correctly and put a dash and no spaces between each).

1

How many amino acids changed due to any mistakes?

1

What group of mutation is this?

1

What type of mutation is this?

1

Which of the two types of mutations had the greatest effect on the protein?
