The chemical evolution theory, proposed by A.I. Oparin in 1923 and later supported by J.B.S. Haldane in 1928, explains the origins of life on Earth. According to this theory, the early Earth was very different from how it is today. To effectively understand this theory, we can explore it through the following categories: Biogeny Chemogeny…

Restriction enzymes (also known as restriction endonucleases) are a group of bacterial enzymes that cleave double-stranded DNA (dsDNA) at specific points, resulting in smaller fragments. These enzymes are used by bacteria as a defense mechanism against invading viruses, limiting their expression. The precise and efficient ability of restriction enzymes to cut large DNA pieces into…
