Genetic markers can be defined as specific DNA sequences with a known location on a chromosome and are essential tools for linkage and association studies. Just select one of the options below to start upgrading. A multiple cloning site (MCS) is present within the lacZ sequence in the plasmid vector. For instance, most plasmids are replicated in E. coli and are relatively small (∼3000 - 6000 basepairs) to enable easy manipulation.

Generation of DNA fragments with overlapping ends - either by restriction digest or PCR. Cloning happens often in nature, as when a cell replicates itself asexually without genetic alteration or recombination. Khan Academy is a 501(c)(3) nonprofit organization.

In the 1950s, a phenomenon known as “host controlled/induced variation of bacterial viruses” was reported, in which bacteriophages isolated from one E. coli strain showed a decrease in their ability to reproduce in a different strain, but regained the ability in subsequent infection cycles (1,2).
