The series of experiments
leading to the discovery of DNA as the genetic material is a perfect
example of how advances in science are made. Biologists use
information collected previously to answer new questions and solve
new problems. Each discovery is a stepping-stone to the next
In this Lesson, we'll look at
how scientists established that DNA holds the hereditary information
and see how the structure of DNA was determined.
We'll also see how DNA's
elegant structure has important implications for DNA replication.
