What are the rules of chemistry in industry and technology?

Why do you have safety rules for the lab?
You have safety rules in a lab, and elsewhere, so you will not hurt yourself or others.

woodward fieser rules is used to determine the max wavelength of absorption spectrum
Does club H20 have rules?

What is the 3 important event that led to understanding the structure of DNA?
Three events that led to understanding the structure of DNA are: Chargaff's Rules, Franklin's Discovery, and Watson and Crick's Model.

What evidence did Watson and Crick use to deduce the structure of DNA?
They applied the clues provided by Chargaff's rules and Franklin's X-ray diffraction studies. Using brass and wire models of the bases, sugars, and phosphate groups, Watson and Crick deduced that the structure of the DNA molecule is a double helix.
Who hypothesized that nitrogen bases in DNA occur in pairs?
James Watson and Francis Crick are credited with the base pairing rules and DNA structure in general. Erwin Chargaff is credited with the rules of base pairs in that the number of pyrimidines is equal to the number of purines.

Who developed the rules for joining DNA?
Erwin Chargaff noticed that adenine and thymine occur in a 1:1 ratio and cytosine and guanine occur in a 1:1 ratio. James Watson and Francis Crick used this discovery, among others, to develop their model of the DNA molecule.
Did erwin chargaff win any nobel prizes?
No, Erwin Chargaff did not win a Nobel Prize. He was an Austrian biochemist who is best known for his research on the composition of DNA, where he discovered the base pair rules known as Chargaff's rules.
What scientists contributed to the discovery of DNA?
Oswald and Avery plus Hersey and Chase were early experimenters that actually showed that DNA, not protein, was the hereditary material. Maurice Wilkins and especially Rosalind Franklin with her X-ray crystallography laid the physical ground work, but it was James Watson and Francis Crick who elucidated the structure of DNA in 1952.
How did Watson and cricks model explain the basis for chargaffs rules?
Watson and Cricks model, the double helix, showed that the base pairs bind together in the centre of the DNA molecule. Therefore because the bases are found in pairs, there must be equal amounts of each. This explained Chargaff's rules - the number of guanine is equal to the number of cytosine and that the number of thymine is equal to the number of adenine - because they are found as pairs.
Why did Rosalind Franklin not get a Nobel Prize for DNA?
2 Reasons: 1) She had died of cancer before the nobel prize for the work on DNA was awarded and the rules of the nobel prizes state that each recipient must be alive for them to receive the prize. 2) her contribution went largely unrecognized until after Watson Crick and Wilkins were awarded the prize.
How is rosalind franklin's contribution to science being used today?
Rosalind Franklin was a member of the Watson - Crick - Wilkins (and others) team working on DNA. It was her crystallography records that were used to develop and prove the dual-helix structure. However she died before the Nobel award was made, and their rules forbid awards given posthumously. You'll find an article on her in wikipedia.org
