Questions 9 to 13 are in reference to the DNA sequence shown in Question 8.

Here is Question 8.

Question 8:

The top strand of the following segment of DNA serves as the template strand:

3’ TACACCTTGGCGACGACT 5’

5’ ATGTGGAACCGCTGCTGA 3’

We will refer to this segment of DNA as the original (or unmutated) sequence.

Please answer the following questions:

(a) What is the mRNA sequence?

The mRNA sequence is  5'  3'.

**Please enter your sequence in the 5' to 3' direction. Deductions will be made if a sequence is inputted in the wrong direction.**

(b) Using the mRNA sequence you determined in part (a) of this question, give the sequence of the protein that would be translated.

The amino acid sequence for this protein is N-terminus  C-terminus.

**Please note**

The N-terminus refers to the beginning of the primary sequence for a protein, and the C-terminus refers to the end of the primary sequence for a protein.

i.e. input the amino acids in the order that they would be translated.

If a codon encodes for a stop codon, type STOP.

When inputting your sequence, separate each amino acid with a hyphen (e.g. Ser-Tyr-STOP).

You will need to consult the genetic code to answer this question.

We will refer to this sequence as mutation #2.

Please note that for simplicity only the template strand for this mutated segment of DNA is shown.

Answer the following questions:

(a) What is the complete mRNA sequence for the mutated segment mutation #2?

The mutated mRNA sequence is  5'  3'.

**Please enter your sequence in the 5' to 3' direction. Deductions will be made if a sequence is inputted in the wrong direction.**

QUESTION 13

Questions 9 to 13 are in reference to the DNA sequence shown in Question 8.

Question 13:

Most mutations have a neutral effect on the phenotype, function or survival of an organism because they do not elicit any noticeable change. Whereas other mutations can have a positive effect on an organism leading to new versions of proteins that help an organism adapt to changes in its environment; while other mutations can have a negative effect on the organism and result in a protein that does not function normally or at all.

Answer the following questions based on the responses you gave above in Questions 8 to 12.

(a) Based on the protein sequences that were produced as a result of mutation #1, mutation #2, or mutation #3, describe the effect, if any, these mutations would likely have on the function of the protein within the cell. Support your answer.

(b) If these mutations occurred within a germline cell and not a somatic cell, how would the effects of these mutations differ?
