Unit 1: DNA Replication and Cell Reproduction.

"It has not escaped our notice that the specific pairing that we have postulated immediately suggests a possible copying mechanism for the genetic material." - Nobel Laureates James Watson and Francis Crick, after solving the structure of DNA in 1953.
