A neuron's ability to generate action potentials depends: Question 1 choices Choice A., on the axon reaching threshold and the o

pening of voltage-gated sodium channels, allowing sodium to enter the axon. Choice B., on the axon reaching threshold and the opening of voltage-gated sodium channels, allowing sodium to leave the axon. Choice C., on the immediate opening of voltage-gated potassium channels once threshold has been reached, allowing potassium to leave the axon. Choice D., on the immediate opening of voltage-gated potassium channels once threshold has been reached, allowing potassium to enter the axon.

Answer is A
Firstly axon must reach the threshold level and then depolarisation occurs. Depolarisation phrase means sodium enters and potassium leaves the axon . Choice C can't be because main idea is the entering of sodium ions.

What do we mean when we say that the genetic code is degenerate?A single codon can encode more than one amino acid.An amino acid
Arada [10]

Answer:

An amino acid can be encoded by more than one codon.

Explanation:

Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.

Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
