How did James Watson and francis crick come to conclusions?
James Watson and Francis Crick are credited with discovering the double helix structure of DNA in 1953. They used X-ray diffraction data produced by Rosalind Franklin and Maurice Wilkins, along with their own model building and theoretical work, to propose the now-iconic structure of DNA. Their breakthrough came from careful analysis, collaboration, and a bit of creative insight.
What was James Watson famous for?
James Watson was famous for alot of things, but a big one was when he graduated at the age of 15 and then later on discovered that DNA was a winding helix in which pairs of bases held the strands together.
What methods did Crick and Watson use to determine the structure of DNA?
Crick and Watson determined the structure of DNA using X-ray crystallography data collected by Rosalind Franklin. They also built physical models and used trial and error to discover the double helix structure of DNA, with the help of base pairing rules proposed by Erwin Chargaff.
do you really think someone that hot/rich would be? i mean come on now

Why is double helix structure of DNA important?
#Herringbone gears are a type of double helical gear, meaning that they have both a left hand and right hand element to cancel thrust or side loading on their bearings. A true herringbone has a 30° helix angle, 20° transverse pressure angle, and an AGMA stub whole depth factor. They may have a center groove between the two hands, but this is not absolutely necessary. Herringbone gears are cut on specialized machines that cut both hands at the same time, precisely locating the apex of the two helixes.
#The double helical form balances the inherent thrust forces.
[Double helical gears, invented by André Citroën and also known as herringbone gears, overcome the problem of axial thrust presented by 'single' helical gears by having teeth that set in a 'V' shape. Each gear in a double helical gear can be thought of as two standard, but mirror image, helical gears stacked. This cancels out the thrust since each half of the gear thrusts in the opposite direction. They can be directly interchanged with spur gears without any need for different bearings.
Where the oppositely angled teeth meet in the middle of a herringbone gear, the alignment may be such that tooth tip meets tooth tip, or the alignment may be staggered, so that tooth tip meets tooth trough. The latter type of alignment results in what is known as a Wuest type herringbone gear.
With the older method of fabrication, herringbone gears had a central channel separating the two oppositely-angled courses of teeth. This was necessary to permit the shaving tool to run out of the groove. The development of the Sykes gear shaper now makes it possible to have continuous teeth, with no central gap.]
#Double helical gears give an efficient transfer of torque and smooth motion at very high rotational velocities.
#A disadvantage of herringbone gears is the high cost due to special gear shaping equipment and special cutting tools.
-Also during assembling a gear box ,aligning is to be given special attention
Describe how watson and crick discoverd the structure of dna?
Watson and Crick used X-ray crystallography data from Rosalind Franklin and Maurice Wilkins to propose the double helix structure of DNA in 1953. They built physical models of the DNA molecule and demonstrated how complementary base pairing allows for the transmission of genetic information. Their discovery revolutionized the field of molecular biology.
What did Watson and Crick do after they discovered DNA?
Watson and Crick did not discover DNA - it had been isolated, then called nuclein, in 1869. What remained unknown was the structure of DNA - this is what Watson and Crick proposed. After they came up with a structure for DNA (1953), they went to 'The Eagle' pub in Cambridge, just round the corner from their lab, and Crick announced to the other customers that he and Watson had discovered 'the secret of life'. The Eagle now has a plaque commemorating the event. They also wrote a letter to Nature, though presumably not while at the pub. Watson and Crick did not discover DNA. What they did was examine the data collected by others, and propose a structure for the DNA molecule.
James Watson is an American molecular biologist and geneticist who, along with Francis Crick, discovered the double helix structure of DNA in 1953. Their work earned them the Nobel Prize in Physiology or Medicine in 1962. Watson has also made significant contributions to the field of genetics and molecular biology.
