Answer:
An amino acid.
Explanation:
Each codon applies to an individual amino acid.
A is the answer according to my notes
Answer:
216 codons
Explanation:
In the RNA molecule there are four types of nucleotide bases, i.e., Adenine, Uracil (Thymine in DNA), Guanine, and Cytosine. In consequence, the number of possible codons or combinations of nucleotide triplets is 64 (4³ = 64 codons). However, these 64 codons code for only 20 different amino acids because multiple codons can code for the same amino acid, it is for that reason that the genetic code is redundant. In this case, if the number of bases would be six (6) instead of four (4) bases, then the number of possible combinations of nucleotide triplets would be 216 codons (6³ = 216).
Rhinoviruses and herpes simplex are just two common viruses out of the other thousands of them that the immune system has to protect the body against.
Answer:
a. It has a negative value.
b. It is measured in millivolts.
c. It is measured in millivolts.
Explanation:
Resting membrane potential is typically ~ -70 millivolts so options a, b and c are correct, rest are false statements.
The resting membrane potential is -70 millivolts because more K+ is inside the neuron while more Na+ is outside the neuron and it reflects more negative voltage in the cytosol as compared to the interstitial fluid.
As soon as stimulus arrives, it causes more Na+ to move inside the neuron making the membrane potential as +20 millivolts and the neuron is said to be in 'depolarized state'. Soon after that K+ starts to move outside of the neuron and since K+ has positive charge and it is moving out of the cell so the membrane becomes more and more negative inside and at this time neuron is said to be in 'hyperpolarised state'.
