An SNP Found in the Conserved Sequence of the Regulatory

Question

An SNP found in the conserved sequence of the regulatory region of a gene is likely to
A)affect protein folding.
B)affect when and where the gene is expressed.
C)be a new mutation.
D)be found in plants as well as humans.

Accepted Answer

A SNP found in the conserved sequence of the regulatory region of a gene is likely to affect when and where the gene is expressed. The regulatory region controls the gene expression and if there is a change in the DNA sequence in this region, it may affect the binding of transcription factors or other regulatory molecules, resulting in altered gene expression patterns. This could lead to changes in the phenotype or disease susceptibility. Affects on protein folding are more likely to be caused by SNPs in the coding region of a gene, and the other two options are not directly related to the impact of a SNP in the regulatory region.
