Why did Watson and Crick refer to the DNA molecule as a double helix?
Because that is the shape of the molecule: two helices wrapped around each other.
Note: due to defective x-ray crystallography photos early in their work, Watson and Crick mistakenly originally reached the tentative conclusion that the DNA molecule was a triple helix with the bases pointing outward, instead of its actual shape of a double helix with the bases pointing inward and linked in pairs by hydrogen bonds.
How did Rev James Cleveland die?
He died of heart failure due to complications from respiratory illness.
How were Richard D. Fairbank and Nigel Morris paid?
Fairbank and Morris chose to receive most of their compensation in the form of stock options
these are too sientists who do biology and made up dna
What was Watson and cricks proposed structure of DNA?
James D. Watson discovered the pattern structure of DNA with Francis Crick.
A purine and a pyrimidine
Watson and Crick discovered that Adenine connects with Thymine and Guanine connects with Cytosine
What places did the stop in Watsons Go To Birmingham 1963?
they started in Flint, then they went to Detroit, then they went to Toledo, then they went to Cincinnati, then they went to Louisville, (it doesn't say that in the book but my teacher told me! :D ) then they went to the Appalachian Mountains, then they went to Birmingham!
There is no indication as of this day March 15, 2010 that he has died. He is now 59 years of age.

Explain the contributions of chargaff Franklin Watson and crick to DNA?
Erwin Chargaff discovered the base pairing rules in DNA, known as Chargaff's rules. Rosalind Franklin's X-ray diffraction images provided key insights into the structure of DNA. James Watson and Francis Crick used this data to propose the double helix structure of DNA. Together, their work laid the foundation for our understanding of DNA.
How did rosalind Franklin's x-ray diffraction affect the work of Watson and crick?
Rosalind Franklin used x-ray crystalography to receive pictures of the DNA
Crick and Watson then used the photo to determine that that the structure of DNA was a double helix - hoped that help :)
How did James Watson discover DNA?
James Watson and Francis Crick discoverd the two strands of nucleotides that form a twisted ladder (double helix) in DNA
Francis Crick was a physicist, molecular biologist, and neuroscientist. He was very well known for being one of the two discoverers (the other being James D. Watson) of the structure of the DNA molecule.
Who to find d-statistic for durbin-Watson test in the gretl program?
run each regressors as dependent variable and leave constant as independent variable. in the next window, click down Tests and choose Durbin Watson. This should give you the DW coefficient and its corresponding pvalue. reject null if less than significance level, accept if more than.
YES NIGGLET ~Apex c;
What obstacles did rosalind Franklin face?
Rosalind Franklin had to rival Cavendish Laboratory scientist Francis Crick at Maurice Wilkins of King's College in 1953.
Who were Francis Crick's brothers and sisters?
Francis Crick had one older brother named Alistair and one younger sister named Gabrielle.
