1. What impacts can mutations have on organisms? Can they be harmful? Can they be beneficial?

2. why every cell does not express all of its genes?

Scenario 1.  

A recent research publication connected migraine headache frequency with a single nucleotide polymorphism.  The affected gene encodes the TRPM8 channel protein that transports ions across a membrane.  Interestingly, this genetic variation may have become common in northern European populations because it also grants them a higher tolerance to cold temperatures

1.  Sequencing of the TRPM8 gene and the surrounding region of the chromosome has been completed.

1. Describe how you know where transcription of this gene would start.
2. Describe how you know where translation of this gene would start.

2.  Using the TRPM8 gene/protein as an example, indicate where you would find this type of bond, what they are made from, and describe how they are formed.

a)  phosphodiester bonds

b)  peptide bonds

3.  A new TRPM8 mutation has been identified in a family in Indiana.  This protein has a missense mutation in the sequence that results in a mutation labelled T118S.

a)  What does this mutation notation indicate?

b)  Using the genetic code, dictate the RNA sequence for this region.

c)  What is the DNA sequence of the template strand for this region?
