Discovery of the structure of DNA (article) | Khan Academy
In this article, we'll briefly explore how the double-helical structure of DNA was discovered through the work of James Watson, Francis Crick, Rosalind Franklin, and other researchers. Then, …
Crick, Watson, and Franklin | DNA structure (article) | Khan Academy
By the 1960s scientists generally embraced the double helix as the structure of DNA, and in 1962 Wilkins, Watson, and Crick received the Nobel Prize in medicine/physiology for their work.
The discovery of the double helix structure of DNA - Khan Academy
How the double helix structure of DNA was discovered. Work of Watson, Crick, Franklin, Wilkins, and Chargaff.
Mode of DNA replication: Meselson-Stahl experiment
Key points: There were three models for how organisms might replicate their DNA: semi-conservative, conservative, and dispersive. The semi-conservative model, in which each …
Classic experiments: DNA as the genetic material - Khan Academy
Additional research by many scientists, including Erwin Chargaff, James Watson, Francis Crick, and Rosalind Franklin, led to the discovery of DNA structure, clarifying how DNA can encode …
Odkrycie struktury DNA (artykuł) | Khan Academy
W tym artykule, pokrótce zgłębimy to, jak została odkryta struktura DNA dzięki pracy James'a Watson'a, Francis'a Crick'a, Rosalind Franklin i innych naukowców. Później przyjrzymy się …
Semi-conservative replication (video) | Khan Academy
Here, we focus on the Meselson-Stahl experiment, which proved DNA replication is semi-conservative. In this process, each new DNA pair consists of one old strand and one new …
Central dogma of molecular biology (video) | Khan Academy
Discover the central dogma of molecular biology, the fundamental process that decodes our genetic information. Learn how DNA replicates itself, how DNA is transcribed into RNA, and …
Hershey and Chase: DNA is the genetic material - Khan Academy
How Alfred Hershey and Martha Chase showed conclusively that DNA is the genetic material.
Descubrimiento de la estructura del ADN - Khan Academy
Watson y Crick reunieron datos de varios investigadores (entre ellos Franklin, Wilkins, Chargaff y otros) para ensamblar su célebre modelo de la estructura 3D del ADN.
