Detailed explanation-1: -Environmental DNA (eDNA) is an emerging scientific method that can be used to better understand ecosystems, environmental change, and stressors. It could prove to be a critical tool for certain purposes/environments, such as assessing the sustainability of fish populations in freshwater bodies.
Detailed explanation-2: -We could give bacteria a helping hand to tackle oil spills on land and at sea by equipping them with enzymes for breaking down hydrocarbons, according to new research. This could be much cheaper and more eco-friendly than other clean-up methods.
Detailed explanation-3: -Pseudomonas putida is a bacterium that is used for scavenging of oil spills by digesting hydrocarbons of crude oil. Pseudomonas is a gram-negative rod-shaped bacteria. It is useful because of its ability to decompose a variety of organic compounds.
Detailed explanation-4: -Recombinant DNA technology is used to make genetically modified organisms (GMOs).
