Answer;
-HaeIII cuts at the sequence GG:CC which is found at nucleotide 143-146 of the TAS2R38 gene. A non-taster alley changes the sequence at position 145 from a C to a G. This makes the gene no longer recognized by the restriction enzyme.
Explanation;
-Restriction enzymes recognize and make a cut within specific palindromic sequences, known as restriction sites, in the genetic code. This is usually a 4- or 6 base pair sequence.
For example; HaeIII is a restriction enzyme that searches the DNA molecule until it finds this sequence of four nitrogen bases.
5’ TGACGGGTTCGAGGCCAG 3’
3’ ACTGCCCAAGGTCCGGTC 5’
Once the recognition site was found HaeIII could go to work cutting (cleaving) the DNA
Answer: the correct answer is option C
C. Oatmeal
Explanation:
It contains soluble fibre. The soluble fibre that is in the oatmeal is capable of attracting water and converting it to gel. This will thicken the bowel and slows down the digestion process hereby increasing the bulk of the bowel. So basically thickening the stool output.
Environmental cues such as drinking a cup of coffee or finishing a meal can induce a craving for nicotine; these cues are known as pairings. In health, these are foods that go well together. It based on the thinking that there are certain flavors in food that match well with each other.
