Linkage studies can map disease genes with a resolution of about one centimorgan.Typically,the physical distance of a DNA region this size is approximately:
A)7.5 × 10² base pairs
B)7.5 × 10³ base pairs
C)7.5 × 10⁴ base pairs
D)7.5 × 10⁵ base pairs

Question

Quizplus · Accepted Answer

One centimorgan (cM) is approximately equivalent to a physical distance of 1 million base pairs (1 Mb) in the human genome. Therefore, the closest option is 7.5 × 10⁵ base pairs, as it is the closest approximation to 1 million base pairs among the given choices.
