Saluting the discoverers of DNA
Boston Globe ^ | 4/24/03 | Kevin Davies

FIFTY YEARS AGO tomorrow, the British science magazine Nature published one of the most astounding scientific reports in history. James Watson and Francis Crick impudently informed the world that they had cracked the molecular structure of the salt of deoxyribosenucleic acid -- better known as DNA. The report included one simple black and white illustration, sketched by Crick's wife, of what has since become universally known as the double helix. The architecture of DNA resembles a twisted ladder that contains some 3 billion rungs labeled in a simple four-letter alphabet -- A, C, G and T -- that spells out the language of life.

You should read up on this since the issue is: the mathematics of Bragg diffaction crystallography
which Franklin understood and W&C did not. THAT is why they relied on modeling.

Furthermore, Wilkins did no work on the key scatter-photograph which was from Franklin
and of a DNA strand WHICH SHE had previously separated
in its form from its A form.

BTW, it is hydrogen bonding which is important and not what you claim.

More importantly, theft, false statements, etc. have no impact on you.
Wilkins took it from her laboratory file and handed it to W&C.

Have a good day.

Diogenesis:

Two points. First, I don't purport to be an expert on X-ray diffraction or its mathematical analysis. If the key to the structure was only the Bragg diffraction data, then why did Dr. Franklin not posit the structure herself? She didn't have the big picture - she couldn't see the forest for the trees. Second, I did mention that one of the most important elements put into context by W&C was the H-bonding between the purines and pyrimidines; Chargaff's findings provided a unifying piece of the puzzle for them to do this. W&C put all the available information into context, "modeling" it as you say. How else could they have done it? To come up with what has proven experimentally to be the true DNA structure was a monumental achievement in the pre-computer days.

I have "read up" on this - starting back in undergraduate school in microbiolgy and biochemistry in the late 70s, culminating with a PhD in 1985 in pharmacology. What are your credentials???

"You believe in DNA?"

(Sorry, but I couldn't resist.)

It's my understanding that Franklin at one point specifically dissavowed the route that Crick & Watson were taking with her x-ray photographs. Salk was also going down the same route as C&W. Was she a brilliant scientist? Unquestionably. Was she responsible for the "AHA" moment which enabled other scientists to use the unlocking of the secret of DNA and vastly expand on the model. I don't think so.

Although her parents were Jewish she had no time for organised religion of any sort.

Had she lived would she have been one of those awarded the Nobel for her work on DNA? Maybe not, but she might have got it for her later work on viruses.

First, she had a right to acquire more data before she published her derived information based upon that data.

Second, she also had a right to not have it stolen by Wilkins,
and/or thereafter by W&C, who egregiously did not even cite appropriately their source.

Not that it matters,did xray diffraction before you were at college and
much other ionizing irradiation work since, as well. Take care.

I'm reading an interesting book by Anne Sayre called Rosalind Franklin and DNA. There is one particularly good chapter where in the space of a few paragraphs she juxtaposes the text of RF's 1951 presentation of her research on the structure of DNA attended by Watson, RF's handwritten notes from that talk, Wilkins's comments, and Watson's comments on this from The Double Helix. It's clearly evident that she knew exactly what she was about, that Watson has expended a great deal of effort in The Double Helix to minimize her contribution, to downplay her ability as a scientist, and to impugn her character by describing her as a flightly, emotionally overwrought and dangerous woman.

At this point I'll say with respect to Wilkins and Watson's role in all this that I'm leaning toward "scum-sucking rat bastards". Later, I'll post these excerpts.

I did not realize that Rosalind Franklin was Jewish.

She was definitely mistreated by the historical record for the omission of her contributions to the DNA double helix recognition.

I read about it years ago, but in what I read there was no mention of her Jewish heritage.

In Watsons book The Double Helix he reveals Franklin’s contributions,then people started to research who Franklin was..
This is all revisionist history,males stole females idea,it is a mans world..
I have never read any place that she was Jewish,i guess you can throw that in as well Jewish and a Female,beaten down by the men sceintists...
