Structure and Discovery of DNA

Vocabulary flashcards covering the key concepts, scientists, and historical milestones in the discovery of the DNA double helix structure as described in the lecture notes.

DNA Location

The nucleic acid found within the nucleus of a cell, specifically located on chromosomes.

Double helical model

The model of DNA structure presented by James Watson and Francis Crick in 1953.

X-ray diffraction studies

The research method conducted by Rosalind Franklin and Maurice Wilkins that provided the foundation for the proposed DNA model.

Photo 51

The famous X-ray diffraction image of DNA taken by Rosalind Franklin that provided crucial information for the discovery of the double helix.

James Watson and Francis Crick

Scientists who presented the double helical model of DNA in 1953 based on X-ray diffraction studies.

Rosalind Franklin

A scientist (1920-1958) who conducted X-ray diffraction studies and produced Photo 51 but passed away at the age of 37 before the Nobel Prize was awarded.

Maurice Wilkins

A scientist (1916-2004) who worked on X-ray diffraction studies of DNA and was co-awarded the Nobel Prize in Medicine in 1962.

1962 Nobel Prize in Medicine

The award given to James Watson, Francis Crick, and Maurice Wilkins for their contributions to the discovery of the DNA double helix model.
