When the DNA structure was discovered what was the first thing noticed?
Watson and Crick
Who was the scientist who did the structure of DNA?
F, Crick and j.Watson discovered the structure of DNA.
Who first correctly described the molecular structure of DNA?
Sir James Watson and Sir Francis Crick first described the molecular structure of DNA correctly. They not only mentioned the fact that DNA is a helical structure, but also described how the constituting molecules are arranged in the helix. The base-pairing, sugar-phosphate backbone were first described by Watson and Crick.
What important discoveries was first found in plants a the structure of DNA b the laws of heredity c the existence of enzymes d the nucleus?
a) The structure of DNA was first discovered in plants by James Watson and Francis Crick in 1953. b) The laws of heredity, also known as Mendelian genetics, were first discovered by Gregor Mendel while studying pea plants in the 19th century. c) The existence of enzymes was first discovered in plants by Eduard Buchner in 1897 when he found that crushed yeast cells could still perform fermentation. d) The existence of the nucleus was first observed in plant cells by Robert Brown in 1831 when he saw a structure inside the cells that appeared different from the rest of the cell.
Which step happens first in DNA replications?
The first thing that happens is a replication structure binds to the DNA molecule. This is usually a signalling molecule or some type of protein. Next, this replication structure attracts DNA helicase enzymes which "unzip" the double stranded helix.

Approximately what was the structure of DNA first described?
1950
How did Watson and crick discover the structure of the DNA?
The discovery of the structure of DNA was a culmative effort. After the discovery that the genes were paired, Watson and Crick suggested the first accurate model of DNA structure in the journal of Nature.
What was james watsons hypothesis for the structure of the dna?
KEY FACT In 1953, James Watson and Francis Crick put forward their hypothesis that DNA had a double helix structure. Their first attempt to identify the structure of DNA was not successful, however, in 1953 they put forward their hypothesis that DNA had a double helix structure.
Who are the 2 men that first described the structure of DNA?
watson and crick
When the DNA structure was discovered what was the first thing noticed?
Watson and Crick
How did Wilkins differ from Watson and Crick in their approach to solving the DNA problem?
Wilkins' X-ray diffraction showed a regular, cyrstal-like structure of DNA. It was when Watson first saw Wilkins' work that his interest in DNA was sparked. Their work overlapped and complemented each other - so differences are difficult to pinpoint.
The tool used to show the structure of DNA was?
The tool used to show the structure of DNA was X-ray crystallography. This technique was used by Rosalind Franklin and Maurice Wilkins to capture the first image of the double helix structure of DNA.
Identify the two men that first described the structure of DNA?
Watson and Crick
