1969: Molecular hybridization of radioactive DNA to the DNA of cytological preparation by Pardue, M. L. and Gall, J. G. 1970: Restriction enzymes were discovered in studies of a bacterium, Haemophilus influenzae, by Hamilton O. Smith and Daniel Nathans, enabling scientists to cut and paste DNA. [44]
Fluorescence in situ hybridization (FISH) is a laboratory method used to detect and locate a DNA sequence, often on a particular chromosome. [4]In the 1960s, researchers Joseph Gall and Mary Lou Pardue found that molecular hybridization could be used to identify the position of DNA sequences in situ (i.e., in their natural positions within a chromosome).
Through the late 1950s and early 1960s, numerous papers were published on various topics in RNA structure, including RNA-DNA hybridization, [22] triple stranded RNA, [23] and even small-scale crystallography of RNA di-nucleotides—G-C, and A-U—in primitive helix-like arrangements. [24]
The 1960s brought us The Beatles, Bob Dylan, beehive hairstyles, the civil rights movement, ATMs, audio cassettes, the Flintstones, and some of the most iconic fashion ever. It was a time of ...
It often increased vigor in plants, and combined desirable traits together. Hybridization most likely first occurred when humans first grew similar, yet slightly different plants in close proximity. [12]: 32 Triticum aestivum, wheat used in baking bread, is an allopolyploid. Its creation is the result of two separate hybridization events. [13]
In 1960, Jacob and collaborators discovered the operon which consists of a sequence of genes whose expression is coordinated by operator DNA. [30] In the period 1961 – 1967, through work in several different labs, the nature of the genetic code was determined (e.g. [ 31 ] ).
Mary Quant has died. The iconic fashion designer's family told multiple outlets that she died at her home in Surrey, England, on Thursday. She was 93.Quant and her eventual husband, Alexander ...
The 1960s were an age of fashion innovation for women. The early 1960s gave birth to drainpipe jeans and capri pants, a style popularized by Audrey Hepburn. [6] Casual dress became more unisex and often consisted of plaid button down shirts worn with slim blue jeans, comfortable slacks, or skirts.
