Question

Quizplus · Accepted Answer

Distances on a physical map of a chromosome are measured in units of base pairs (bp), as this is the most basic unit of measure for DNA. SNPs and RFLPs are genetic markers that can be used to map genes or other sequences on a chromosome, but they do not provide a measure of physical distance. CentiMorgans (cM) are a measure of genetic distance that takes into account the frequency of recombination events between two loci, but they do not provide a direct measure of physical distance. Contigs are a term used in genome sequencing to describe overlapping sets of DNA fragments that can be assembled into a contiguous sequence.
