a nonsense mutation.
a frameshift mutation.
both b and c.

Expert Solution & Answer

Summary Introduction

Introduction:

The mutation can be described as a condition in which the nucleotide sequence of the DNA is altered. Even a single change in nucleotide may result in many consequences.

Answer to Problem 1TY

Option (d).

Explanation of Solution

Explanation for Correct Answer:

Option (d) frameshift mutation. The frameshift mutation occurs due to a deletion or insertion of nucleotide, which is not a multiple of 3. It causes the shifting of the entire reading frame of DNA sequence, which is the reason it is named so. Sometimes, frameshift mutation may cause deletion of a nucleotide and resulting in a premature presence of stop codon and terminate the sequence prior resulting in short polypeptide or inactivation of the gene product. Hence, it is the correct answer.

Explanation for the incorrect answer:

Option (a) silent mutation. The silent mutation results in the change of nucleotide but does not affect the amino acid or protein formed by that. Hence, it is an incorrect answer.

Option (b) missense mutation. The missense mutation is a mutation that results in the change of nucleotide and replaces the amino acid in the protein sequence, but the length of the sequence remains unaffected. Hence, it is an incorrect answer.

Option (c) nonsense mutation. The non-sense mutations can be described as point mutation which results in the occurrence of a premature stop codon due to the replacement of a nucleotide. In this mutation, the presence of stop codon before the end of the sequence result in early termination of the amino acid formation and result in shorter polypeptide. Hence, it is an incorrect answer.

Option (e) both (b) and (c). As both the option (b) and (c)are incorrect answers, this is also an incorrect option.

One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?
