Question

chromosomes contain genes, and genes determine an organisms characteristics. sometimes mutations occur in which the sequence of nucleotides within a gene becomes altered. which of the following describes how a gene mutation would most likely affect an organism? a. it would cause different proteins to be produced during translation. b. it would cause the codons produced to be more or less than 3 nucleotides in length. c. it would cause the sugar - phosphate backbone of all of the organisms dna to be modified. d. it would cause the wrong type of nucleic acid to be incorporated into the organisms genes

Explanation:

A gene mutation changes the DNA sequence. During translation, the altered DNA sequence can lead to different proteins being produced. Option A is correct as it describes this relationship accurately. Option B is wrong as mutations don't typically affect the length of codons in that way. Option C is incorrect because mutations don't directly modify the sugar - phosphate backbone of all DNA in that manner. Option D is wrong as mutations don't cause the wrong type of nucleic acid to be incorporated into genes.

Answer:

A. It would cause different proteins to be produced during translation.
