Watson Crick Franklin and Wilkins

Watson and Crick used X-ray crystallography data from Rosalind Franklin and Maurice Wilkins to create a model of DNA's double helix structure. They then built physical models and made a series of deductions to propose the now-famous double helix structure of DNA.

According to the Watson-Crick model, DNA is a double helix structure made up of two complementary strands that are held together by hydrogen bonds between the nitrogenous bases. The four nitrogenous bases are adenine, thymine, cytosine, and guanine. DNA is a stable molecule due to the hydrogen bonding between base pairs and the helical structure that protects the genetic information stored within the molecule.

James Watson and Francis Crick were co-discoverers of the double helix structure of DNA in 1953. Their work revolutionized the field of molecular biology and earned them the Nobel Prize in Physiology or Medicine in 1962. Their discovery laid the foundation for modern genetics and our understanding of heredity.

James Watson and Francis Crick are credited with being the first to discover the di-basic double helix structure of (B form) DNA (published in Nature in 1953) at the Cavendish Laboratory, Cambridge University. Important in their discovery were unpublished X-ray diffraction images of DNA created by Rosalind Franklin at Kings College, London shown to them by her colleague Maurice Wilkins.

They won the Nobel prize for Physiology or Medicine in 1962 jointly with Maurice Wilkins (sadly, Rosalind Franklin had died of cancer in 1958 and thus was not eligible for the prize). James Watson is still working and Francis Crick died in 2004.

The Watson and Crick model suggested that DNA replicates by separating its two strands and using each strand as a template to build a new complementary strand. This process follows the principle of complementary base pairing, where adenine pairs with thymine and guanine pairs with cytosine.

The work of Chargaff, Wilkins, and Franklin formed the basis for the discovery of the double-helix structure of DNA by Watson and Crick in 1953. Their research on the chemical composition and x-ray diffraction patterns of DNA provided crucial insights that helped in deciphering the structure of the DNA molecule.

Rosalind Franklin's work with X-ray diffraction involved exposure to high levels of radiation, which can damage DNA and increase the risk of cancer. This prolonged exposure to X-rays likely contributed to her development of cancer at an early age.

James Watson and Francis Crick proposed the current DNA structure model in 1953, which is known as the double helix.

Mr Samuels hates Dr. Wyatt because he blames him for Miss Trent's death. He believes Dr. Wyatt's experiments were reckless and unethical, leading to a tragic outcome. Mr. Samuels holds Dr. Wyatt responsible and seeks justice for what he sees as a preventable loss.

DNA's double helix structure allows for easy replication and transmission of genetic information from one generation to the next. The sequence of nucleotides encodes the genetic instructions for building and maintaining an organism, ensuring that specific traits are passed down from parents to offspring. Additionally, its stability and ability to store vast amounts of information make it a reliable and efficient hereditary molecule.

The most basic DNA structure is a double helix composed of two complementary strands of nucleotides held together by hydrogen bonds. Each strand consists of a sugar-phosphate backbone with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugars.

Wilkins and Franklin contributed to the discovery of the structure of DNA by using X-ray crystallography to produce images that revealed the helical nature of DNA. Their work provided key insights that were essential for James Watson and Francis Crick to propose the double helix model of DNA.

No, Francis Crick did not change his career in physics when a bomb fell into his lab during World War II. This event did not deter him from pursuing his interest in science, specifically in the field of biology. Crick went on to co-discover the structure of DNA along with James Watson, which revolutionized the field of molecular biology.

X-ray diffraction data of DNA revealed its double helical structure, with specific measurements indicating a helical repeat distance of around 3.4 angstroms and a complete turn every 10 base pairs. This data was crucial in understanding the molecular structure of DNA and its role in genetic information storage and replication.

Yes, in 1953 there was a bomb scare that occurred near Francis Crick's laboratory at the Cavendish Laboratory in Cambridge, UK. The bomb fell through a window, but it did not explode, and no one was injured.

Rosalind Franklin's X-ray diffraction images of DNA revealed a helical structure with a consistent diameter and regular twisting pattern. This data suggested a double helix shape for DNA, which was essential for Watson and Crick in developing their accurate model of DNA's structure. Franklin's evidence provided crucial insights into the physical form of DNA, leading to the correct understanding of its double helix structure.

In the Watson and Crick model of DNA, the steps of the ladder are composed of nucleotides. Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). These nucleotides are linked together through phosphodiester bonds to form the backbone of the DNA molecule.

Why is anyone racist? There really isn't any answer to this question other than his upbringing and experiences probably lead him to disparaging views of certain ethnicities and women. It's unfortunate considering his discoveries in the field of genetics, but his comments and attitude (especially concerning Franklin) have marred his achievements and character.

Rosalind Franklin, a biophysicist, used X-ray diffraction to capture images of DNA's structure. These images provided crucial data that helped Watson and Crick in determining the double helix structure of DNA.

Francis Crick is well known for co-discovering the structure of DNA with James Watson in 1953, for which they were jointly awarded the Nobel Prize in Physiology or Medicine in 1962. Crick's contributions to the field of molecular biology and his work on the genetic code have also had a lasting impact on the scientific community.

Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.

DNA polymerase was first discovered in 1956 by Arthur Kornberg and his team at Washington University in St. Louis. They isolated the enzyme from E. coli bacteria and demonstrated its role in DNA replication.
