Recombinant DNA (rDNA) refers to artificial DNA molecules that are created by combining genetic material from different sources. This technology involves the insertion of DNA fragments from one ...

Recombinant DNA technologies developed in the early 1970s enabled scientists to isolate genes of interest and splice them into existing DNA structures. However, as late as the early 1980s, the ...

Researchers uncovered the foundations of biology by using E. coli as a model organism. But over-reliance on this microbe can lead to knowledge blind spots with implications for antibiotic resistance.
