Amutation results in an organism that lacks the ability to make one amino acid .what is true of this organism ?
a. the organism's ability to rna has been changed
b. a gene has undergone a change in the organisms dna
c. ribosomes in the organism do not function properly
d. all the above

The correct answer is-

b. a gene has undergone a change in the organisms DNA.

DNA ( deoxyribonucleic acid) contains instructions for protein synthesis in the form of codons ( a sequence of three nucleotides), which code for particular amino acid. DNA is converted to mRNA ( through transcription), which is then converted to proteins ( through translation).

As per the question, a mutation in an organism has lacked the ability to make ( incorporate) one amino acid.

This means that there is a change in the codon ( that is change in the gene) in a manner such that now the mutated codon will not code for any amino acid.

Thus, option b) is the right answer.
