Gene 'hops' into prey in surprising predator-prey transfer observed by scientists

Jumping genes are responsible for the spread of antibiotic resistance and in the development of many cancers. Scientists are also studying circular RNA molecules, like the one derived from the jumping intron, as next generation vaccine platforms. Understanding jumping genes can thus have profound implications for medicine

Quick Revision

Prelims-testable facts

01Horizontal gene transfer is the process by which genes are transferred between species without a viral courier.
02The phenomenon of horizontal gene transfer can lead to the rapid acquisition of new traits, such as antibiotic resistance.
03Circular RNA molecules play a crucial role in facilitating the transfer of jumping genes between species.
04Jumping genes have been linked to the development of various cancers and are also responsible for the spread of antibiotic resistance.
05The study of horizontal gene transfer provides insights into how organisms can rapidly acquire new traits, including those that confer advantages or disadvantages.
06Horizontal gene transfer across species without a viral courier has been observed directly in a bacterial predator-prey system.

Trap alerts

Most people think jumping genes are only transferred between species through viruses, but actually they can also be transferred through predation and other mechanisms.
Most people think horizontal gene transfer is a slow process, but actually it can occur rapidly due to the presence of circular RNA molecules.
