Depend if you are more creative or more a solver(good in math).
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.
Answer:
The answer would be physical.
Explanation:
This is the answer because it is showing all of the physical features of the map.
Answer:
A-G-C-U-C-A
Explanation:
A-G-C-U-C-A is the base sequence correctly represents the corresponding portion of RNA molecule if DNA molecule with the base sequence A-G-C-T-C-A was used as a template. It is because the RNA molecule is formed from the same bases used in DNA except thymine. In RNA molecule, instead of thymine, uracil is attached with other nucleotide bases.
