Thursday April 4th
The Beta3-adrenergic
receptor gene makes a protein in fat
cells that is involved in determining how much fuel your body burns when you
are resting. A mutation in this gene slows down how quickly a person burns fat
— increasing their tendency to be obese. A mutation is any change in the
nucleotide sequence. What will a
change in the DNA sequence affect during transcription?
A change in the DNA will ultimately then change the RNA sequence during transcription.
During what process is the
protein built that will be faulty? Translation. - Now this faulty mRNA sequence will be "read" wrong and produce an altered protein.
We then started into the process of translation while using models to work through it. See the slides and pictures below.
