DNA Double Helix

The double helix structure of DNA was first discovered in 1953 by James Watson and Francis Crick. The structure allows for DNA to be tightly packed into chromosomes. It provides an extremely stable backbone and so makes it difficult to be destroyed.


The study of living things is an accepted definition of biology but this STEM career path is as diverse as life on planet Earth and even beyond. Biologists often specialize in researching an organism of particular interest like entomologists and botanists while others may specialize in a field of study across organisms like geneticists and physiologists. Whatever the chosen interest biologists are critical to many sectors of the workforce including medicine, research institutions, conservation, law enforcement, politics, and education! One thing is certain, a deep curiosity and love of problem solving will take you far as a biologist.
