Which polymorphism is most likely to affect an individual's phenotype?
A)An SNP in an intron of a protein-coding gene
B)An SSR within a telomeric sequence
C)A DIP in an intragenic region between genes
D)An SNP in the start codon of a protein-coding gene

Question

Quizplus · Accepted Answer

An SNP (Single Nucleotide Polymorphism) in the start codon of a protein-coding gene is most likely to affect an individual's phenotype because the start codon is crucial for initiating translation. Alterations here can disrupt the production of the encoded protein, directly impacting the phenotype.
