Question

A normal bacterial cell carries on the chemical reaction A----------->B. A certain mutant bacterial cell cannot produce substance B. The mutation was most likely the result of a change in the..
1. Ribosome on which enzyme X is made

2. Ability of the DNA to replicate

3. Amino acid sequence of RNA


4. Gene that codes for enzyme X

Answer 1

The answer is 4 have a good day

Answer 2

Answer:

The correct answer is option 4. Gene that codes for enzyme X

Explanation:

Hello!

Let's solve this!

Mutations are a change in the DNA sequence.

We will analyze each of the options:

1. Ribosome on which enzyme X is made: the ribosome cannot suffer mutations.

2. Ability of the DNA to replicate: DNA can suffer mutations, but will not affect the production of substances.

3. Amino acid sequence of RNA: RNA does not suffer mutations

4. Gene that codes for enzyme X: This option is correct because when the gene undergoes a mutation, the enzyme that is encoded by that gene will be affected.

After the analysis we conclude that the correct answer is option 4. Gene that codes for enzyme X
