Answer:
5’ – TAC-GCA-CTG-3’
Explanation:
As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.
Purines include adenine (A) and cytosine (C)
Pyrimidine include thymine (T) and guanine (G)
Thus an A always pair with T and C always pair with G
Thus, the resulting poly peptide for the given amino acid sequence is
3'-ATG-CGT-GAC-5'
5’ – TAC-GCA-CTG-3’
The right answer is <span>Refractory period.
At the moment when the action potential is emitted, the fiber being depolarized, it is impossible to depolarize it again. It is, therefore, necessary to wait until the membrane potential returns to a value below the critical threshold in order to be able to excite it again. We are thus led to distinguish two periods that characterize its excitability.
An absolute refractory period: during which any stimulation, even supraliminal, is ineffective since the fiber is already depolarized.
A relative refractory period: during which a second action potential can be omitted provided that the depolarization produced by the excitation reaches the critical threshold, which implies that it is more important since the value of the resting potential has not been restored yet.</span>
<span>Pepsin is an enzyme that breaks down proteins into amino acids in the stomach (where the pH is 1-3). Pepsin needs to be in an acidic environment to be activated. The optimum temperature is between 30 oC and 40 oC because the average human body temperature is 37 oC. The optimum pH is the acidic one because your stomach has an acidic pH.</span>
