Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied “trait inheritance“, patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete “units of inheritance“. This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Source: Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. Source: CRISPR is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. Hence these sequences play a key role in the antiviral (i.e. anti-phage) defence system of prokaryotes and provide a form of acquired immunity. CRISPR is found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea. Source: According to Greek mythology, the Chimera, Chimaera, or Chimæra was a monstrous fire-breathing hybrid creature from Lycia, Asia Minor, composed of different animal parts. It is usually depicted as a lion, with the head of a goat protruding from its back, occasionally depicted with dragon's wings, and a tail that might end with a snake's head.[3] It was an offspring of Typhon and Echidna and a sibling of monsters like Cerberus and the Lernaean Hydra. Source: (mythology) The Nephilim are mysterious beings or people in the Hebrew Bible who are described as being large and strong. The Hebrew word Nephilim is sometimes translated as “giants“, and sometimes as its literal meaning “the fallen ones“. Their origins are disputed. Some, including the author of the Book of Enoch, view them as offspring of fallen angels and humans. Others view them as offspring of the descendants of Seth and Cain.
