ss7ja [257]
Answer - The chromosomes has to be crucially duplicated and it happens actively during the resting phase or interphase.

Reasoning - During the resting phase or interphase you call it, Is important to have the same exact DNA or Chromosomes to be duplicated. If the chromosomes did not duplicate during the interphase then the split of the cell would be unbalance and uneven and likely to cause defects.

Generally speaking, which of the following mutations would most severely affect the protein coded for by a gene?a) a base substi
Pavlova-9 [17]

Answer:

Answer is C.

Explanation:

For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.

Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
