Colligative properties are those properties of solutions that depend on the number of dissolved particles in solution, but not on the identities of the solutes. For example, the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water.
Shares & Saves. Save. DNA testing evolved from the study of genetics, which began in the late 1800s when Gregor Mendel first studied the phenomenon of inherited traits in pea plants. His work laid the foundation for the discovery of DNA, or deoxyribonucleic acid, the molecules that contain our genetic makeup.
DNA (Or DeoxyriboNucleic acid) was never invented; it has existed on earth for as long as life has been present, though people did find out about it eventually. The shape of â¦ DNA was discovered in 1953 by Francis Crick and James Watson. DNA was discovered to be the genetic material in the 1944 by Avery and coworkers.NA (Or DeoxyriboNucleic acid) was never invented; it has existed on earth for as long as life has been present, though people did find out about it eventually.
