Ragos y herencia: ADN

In the mid-20th century, scientists like Watson, Crick, and Franklin advanced our understanding of DNA, identifying it as the genetic material in genes. DNA is structured as a twisted ladder, known as a helix, with rungs made of nitrogen bases. These bases pair in specific ways, forming the genetic code that determines hereditary traits.

Which scientists were involved in the discovery of DNA as the genetic material?

• Albert Einstein and Niels Bohr

• Martha Chase and Alfred Hershey

• Isaac Newton and Galileo Galilei

• Marie Curie and Louis Pasteur
