Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation’s probability of being deleterious.

Detailed explanation-2: -Most mutations are not harmful, but some can be. A harmful mutation can result in a genetic disorder or even cancer. Another kind of mutation is a chromosomal mutation. Chromosomes, located in the cell nucleus, are tiny threadlike structures that carry genes.

Detailed explanation-3: -Mutations to this 10 percent can be neutral, beneficial, or harmful. Probably less than half of the mutations to this 10 percent of DNA are neutral. Of the remainder, 999/1000 are harmful or fatal and the remainder may be beneficial.

Detailed explanation-4: -Mutations can add, delete, or substitute nucleotides within the sequence of a gene. Because many codons specify the same amino acid, many mutations are completely harmless.

Detailed explanation-5: -ATP. Carbohydrates. Condensation Reaction. DNA and RNA. DNA replication. Denaturation. Enzymes. Factors Affecting Enzyme Activity. More items
