Answer:
Competition on the same receptor binding site
Explanation:
Adenosine is a neuromodulator or chemical in nervous system that makes humans feel tired while caffeine act as adenosine antagonist of adenosine blocker that makes human feel fresh.
Adenosine and caffeine both binds to the same receptor and compete for the same binding site. When adenosine binds to its receptors, the neural activity slows down but when caffeine binds to the same receptor, it do not allow adenosine to bind the same receptor and do not slows down the neural activity.
Hence, the correct answer is "Competition on the same receptor binding site".
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

<span>I have to talk to you. I appreciate your humor but lately you've really been putting me down in front of my friends, and it's been bothering me. I know you don't mean it, but you've been hurting my feelings and making me feel insignificant in front of my friends. Do you think you can try not to do that anymore?</span>
Pharmacy technicians can help patients understand possible drugs side effects by explaining to them the effects [both positive and negative] that the drugs they are buying will have on them.They can also educate patients about drug use and effects with the aid of information sheets.
