Question 4 (WRONG) 1. Two people have diﬀerent versions of an SNP, such that one has the codon CCC and the other the codon CAC. Assuming that the SNP is in a gene and therefore inﬂuences the protein sequence, under which of the following scenarios is the SNP likely to result in a protein with altered structure (select all that apply)?
