Sphynx cats have a mutation in a(n)_____ of the keratin gene, which prevents necessary splicing; therefore, keratin protein fibers do not assemble properly.
A) promoter
B) intron-exon splice site
C) exon
D) stop codon
E) enhancer

Question

Quizplus · Accepted Answer

The correct answer is B) intron-exon splice site because mutations in these sites can prevent the proper removal of introns during RNA processing, leading to improperly assembled keratin protein fibers. This is because the splicing process, which removes non-coding introns and joins coding exons, is crucial for generating a functional mRNA that can be translated into a protein. A mutation in the intron-exon splice site would disrupt this process, affecting the protein's assembly.
