In 1960, Jacob and collaborators discovered the operon which consists of a sequence of genes whose expression is coordinated by operator DNA. [30] In the period 1961 – 1967, through work in several different labs, the nature of the genetic code was determined (e.g. [ 31 ] ).
1989: Thomas Cech discovered that RNA can catalyze chemical reactions, [60] making for one of the most important breakthroughs in molecular genetics, because it elucidates the true function of poorly understood segments of DNA. 1989: The human gene that encodes the CFTR protein was sequenced by Francis Collins and Lap-Chee Tsui.
[68] [69] In 2015, the 40,000 year old modern human Oase 1 was found to have had 6–9% (point estimate 7.3%) Neanderthal DNA, indicating a Neanderthal ancestor up to four to six generations earlier, but this hybrid Romanian population does not appear to have made a substantial contribution to the genomes of later Europeans.
2003: The Human Genome Project sequences the human genome with a 92% accuracy. [132] 2004: Ben Green and Terence Tao announce their proof on arithmetic progressions in prime numbers known as the Green–Tao Theorem. 2004: Andre Geim and Konstantin Novoselov isolated graphene, a monolayer of carbon atoms, and studied its quantum electrical ...
1972 – The DNA composition of chimpanzees and gorillas is discovered to be 99% similar to that of humans. 1973 – Stanley Norman Cohen and Herbert Boyer perform the first successful recombinant DNA experiment, using bacterial genes. [6] 1974 – Scientists invent the first biocement for industrial applications.

Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
Recombinant DNA is a man-made DNA sequence that has been assembled from other DNA sequences. They can be transformed into organisms in the form of plasmids or in the appropriate format, by using a viral vector . [ 159 ]
