What would most likely happen is an error occurred when rna was receiving coding information? a: proteins would be formed incorrectly . b: dna would for incorrectly . c: rna could not form a correct blueprint. d: the incorrect amino acid would form .

The right answer is A: proteins would be formed incorrectly.

During DNA replication, transcription errors are likely to occur during polymerization of the second DNA strand by DNA polymerase. These errors, called mutations, can have consequences on the phenotype of a living being, especially if they occur in the coding regions of a gene. The error rate is generally very low, of the order of one replication error out of ten to one hundred million replicated bases, thanks to the function of proofreading of DNA polymerases.

Missense and nonsense mutations are examples of point mutations that can cause genetic diseases such as thalassemia and sickle cell disease, by changing the physicochemical nature of an amino acid residue important for the function of the modified protein.

The correct answer is -

A: proteins would be formed incorrectly.

RNA (ribonucleic acid) receives coding information from DNA during the process of transcription (DNA to mRNA). Genetic information is transferred from DNA to RNA in the form of codons (sequence of three nucleotides that code for particular amino acid).

mRNA (messenger RNA) is then converted to particular protein through translation.

If error occured when RNA was receiving coding information, it means that there was alteration in the codon sequence, which will ultimately result in the incorrect protein formation during translation.

Thus, option A) is the right answer.

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.
