Why are housekeeping genes not used to create DNA fingerprints?
A) They mutate often because they are unnecessary genes and so are highly variable.
B) They are important genes for every cell in every person and so are highly conserved.
C) They are found only in a few cell types, not all cell types.
D) They are expressed at a low rate in cells.

Question

Quizplus · Accepted Answer

Housekeeping genes are highly conserved because they are essential for basic cellular function and are present in all cells, making them unsuitable for DNA fingerprinting, which relies on variability.
