At the initiation complex of translation in eukaryotes,
a) the complex of mrna and the large ribosomal subunit are formed.
b) the anticodon of trna charged with methionine binds to mrna associated with the small ribosomal subunit.
c) the large ribosomal subunit binds to mrna, causing the release of the small subunit.

B) the anticodon of tRNA charged with methionine binds to mRNA associated with the small ribosomal subunit.

Explanation:

Translation:

Translation is the process occurring within living organism by which message from mRNA is translated into protein.

Eukaryotic translation consists of four phases: initiation, elongation, termination, and recycling

Here in this question discussion on Initiation is needed.

Translation initiation

Translation initiation in eukaryotes initiates when eukaryotic initiation factors (eIFs) assembles tRNA, 40S, and 60S ribosomal subunits at the initiation codon of mRNA into an 80S ribosome .

These eukaryotic initiation factors (eIFs) holds the mRNA in place and bind the 40S ribosomal subunit.

Correct

The tRNA anticodon charged with amino acid methionine binds to start codon AUG of mRNA associated with the small ribosomal subunit.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
