Question

question 7 of 10
how could an error during transcription affect the protein that is produced?
a. the protein would have the wrong shape.
b. the protein would be made of the wrong nucleic acids.
c. the protein would become too specialized.
d. the protein would become rna polymerase.

Explanation:

Transcription is the process of making mRNA from DNA. The mRNA sequence determines the amino - acid sequence of the protein (during translation). An error in transcription can change the mRNA sequence. Since the amino - acid sequence (primary structure) determines the protein's shape (through folding, which is based on interactions between amino acids), a wrong mRNA sequence (due to transcription error) can lead to a wrong amino - acid sequence and thus a wrong - shaped protein. Proteins are made of amino acids (not nucleic acids, so B is wrong). There's no basis for a protein becoming "too specialized" (C is wrong) and a protein won't become RNA polymerase (D is wrong as they are different types of molecules with different functions).

Answer:

A. The protein would have the wrong shape.
