Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .

Watson and Crick knew that the triple helix model of DNA that Linus Pauling had proposed was incorrect What evidence did they have for such a conclusion?

Watson and Crick had evidence indicating that the width of the DNA molecule suggested a double helix rather than a triple helix. Additionally, base pairing rules they proposed provided a more plausible explanation for the structure of DNA. These findings led them to conclude that the triple helix model was incorrect.


What evidence did watson and crick use to disprove linus paulings triple helix thery?

Watson and Crick used X-ray diffraction data and molecular modeling to disprove Linus Pauling's triple helix theory of DNA. Their analysis showed that the structure of DNA was a double helix, not a triple helix as proposed by Pauling. This discovery revolutionized the understanding of DNA structure and function.


Which scientist added an extra strand to the structure of DNA and won two Nobel Prizes?

Linus Pauling is the scientist who proposed a triple helix structure for DNA with an extra strand. However, this model was later proven incorrect. Linus Pauling won the Nobel Prize in Chemistry in 1954 and the Nobel Peace Prize in 1962.


The double-stranded structure of a DNA molecule is referred to as the?

The double helix.


What is the name for double stranded DNA?

DNA is a double-stranded nucleic acid.


What is major difference between normal DNA helix and RNA helix?

DNA is double stranded while RNA only has one strand.


What is the major difference between normal DNA double helix and RNA double helix?

The major difference is that RNA is usually single-stranded while DNA is double-stranded. Additionally, RNA contains uracil as one of its bases instead of thymine found in DNA. RNA is also usually more transient and involved in a wider variety of functions than DNA.


Is a DNA a single stranded?

DNA is a double helix structure like a twisted ladder


What is a description of the structure of DNA and RNA?

DNA is double stranded whereas RNA is single stranded . They are different in their functioning as well .


What are the two strands of a double stranded chromosome called?

The two strands of a double-stranded chromosome are called chromatids. Each chromatid contains a single DNA molecule that is duplicated and bound to its sister chromatid at the centromere.
