Our year 10 science class have been studying genetics and DNA with Mr Walker.
The chemical DNA was first discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. In 1953, James Watson and Francis Crick, aided by the work of biophysicists Rosalind Franklin and Maurice Wilkins, determined that the structure of DNA is a double-helix polymer, a spiral consisting of two DNA strands wound around each other. The breakthrough led to significant advances in scientists’ understanding of DNA replication and hereditary control of cellular activities.
DNA contains the information that builds us and our unique features that we inherit from our parents
The students built models of the molecule for DNA, and then they extracted DNA from strawberries.
