A brief introductionEdit
Welcome to my userpage. I'm User:ChamithN and I started editing Wikipedia in 2014. I mainly edit articles related to computer science and entertainment; however, I'd be glad to help if someone needs my assistance for articles outside of my comfort zone. I tend to make a lot of typos over the course of editing. So, if you come across any (even in my talk page comments), feel free to revert/fix them, and/or ask me for clarification. I believe in WP:BRD cycle; ergo, I'm always up for civil and meaningful discussions. If you have any questions regarding editing Wikipedia, feel free to ask at the Teahouse or my talk page.
Picture of the dayEdit
(June 16, 1902 – September 2, 1992) was an American scientist and one of the world's most distinguished cytogeneticists
. After receiving her PhD in botany from Cornell University
in 1927, McClintock began studying chromosomes
and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of these was the notion of genetic recombination
by crossing over
– a mechanism by which chromosomes exchange information. McClintock produced the first genetic map
for maize, linking regions of the chromosome to physical traits. She also demonstrated the role of the telomere
and the centromere
, regions of the chromosome that are important in the conservation of genetic information
. Recognized as among the best in the field, she received the 1983 Nobel Prize in Physiology or Medicine
This 1947 photograph, in the collection of the Smithsonian Institution Archives, shows McClintock in her laboratory at the Cold Spring Harbor Laboratory in Laurel Hollow, New York.Photograph credit: Science Service, Smithsonian Institution; restored by Adam Cuerden
