What did Margarita Salas discover?
Margarita Salas discovered a new mechanism for the replication of DNA. The enzyme she isolated as the key to it has transformed the process of amplifying DNA from very small samples, and is now widely used in forensics, studies of ancient DNA and oncology, as well as in basic research.

Where did Margarita Salas do her work?
Severo Ochoa Center for Molecular Biology
Salas was a professor of molecular genetics at the Complutense University Faculty of Chemistry from 1968 to 1992. She was also a professor of research at the Severo Ochoa Center for Molecular Biology in Madrid from 1974, and its director from 1992 until January 1994.
Why is Margarita Salas famous?
Margarita Salas Falgueras was a researcher in the fields of biochemistry and molecular genetics. She is best known for her studies on DNA, especially the discovery and characterization of Φ29 phage DNA polymerase. This enzyme allows the amplification of DNA traces into amounts that are large enough for analysis.
Why was Rosalind Franklin not awarded the Nobel Prize?
Lise Meitner and Otto Hahn in their laboratory, 1913. There’s a very good reason that Rosalind Franklin did not share the 1962 Nobel Prize: she had died of ovarian cancer four years earlier and the Nobel committee does not consider posthumous candidacies.
Who created DNA?
Friedrich Miescher
DNA was discovered in 1869 by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells (white blood cells). Instead, he isolated a new molecule he called nuclein (DNA with associated proteins) from a cell nucleus.
Did Rosalind Franklin get credit for her work?
Franklin, whose lab produced the photograph that helped unravel the mystery of DNA, received no credit for her role until after her death. Since the Nobel Prize committee doesn’t confer awards posthumously, it means that Franklin will never share in the scientific community’s highest honor for her work.
When did DNA first appear on Earth?
some 4 billion years ago
According to the authors of the study, these results suggest that the earliest DNA molecules could have appeared in parallel with RNA – some 4 billion years ago. This would mean that DNA molecules emerged around 400 million years earlier than previously thought.
