Question

1. a normal bacterial cell carries out the chemical reaction represented in the diagram below.

a certain mutant bacterial cell cannot produce substance b. the mutation was most likely the
result of a change in the -
a enzyme x b

clear all
gene that codes for enzyme x
amino acid sequence of rna
ability of the dna to replicate
ribosome in which enzyme x is made

Explanation:

Enzymes are proteins, and proteins are encoded by genes. A mutation in the gene that codes for enzyme X would likely prevent the production of functional enzyme X, thus stopping the reaction \(A
ightarrow B\) (since enzyme X is needed for this reaction). RNA has an amino - acid sequence based on DNA, but the main issue here is the gene (DNA segment) for the enzyme. DNA replication ability is not directly related to the production of a specific enzyme for this reaction. Ribosomes are involved in protein synthesis, but the root cause of not producing enzyme X (and thus substance B) is a mutation in the gene for enzyme X.

Answer:

gene that codes for enzyme X
