Watson Crick Franklin and Wilkins

James Watson and Francis Crick unraveled the structure of DNA, which is a double-helix molecule that carries genetic information in cells. Their discovery in 1953 laid the foundation for modern molecular biology.

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.

Crick and Watson used X-ray diffraction data collected by Rosalind Franklin to propose the double helix structure of DNA. They also used model-building and trial-and-error methods to refine their proposed structure. Their discovery laid the foundation for understanding how genetic information is stored and passed on in living organisms.

James D. Watson received a Bachelor of Science degree in zoology from the University of Chicago in 1947 and a Ph.D. in zoology from Indiana University in 1950.

James Watson, along with Francis Crick and Rosalind Franklin, discovered the double helix structure of DNA in 1953. This groundbreaking finding revolutionized the field of genetics and laid the foundation for further research in molecular biology.

Watson and Crick developed the double helix model to describe the three-dimensional structure of DNA, demonstrating how the molecule is composed of two strands that are twisted together like a spiral staircase. This model revolutionized our understanding of genetics and provided insights into the mechanism of genetic replication and heredity.

Louis Pasteur settled the spontaneous generation argument by conducting experiments that showed microorganisms do not appear out of thin air but rather are introduced from external sources. His swan-neck flask experiment demonstrated that air could still reach the liquid inside the flask, but dust particles containing microorganisms were trapped in the curved neck, preventing contamination and disproving the idea of spontaneous generation.

In the Watson-Crick model of a double helix, the steps of the spiral staircase are composed of nitrogenous bases. These bases include adenine (A) pairing with thymine (T) and cytosine (C) pairing with guanine (G) through hydrogen bonds.

Watson and Crick deduced the double helix structure of DNA. They proposed this model in 1953, revolutionizing our understanding of genetics and molecular biology.

Francis Crick and James Watson used data from other scientists, including Rosalind Franklin's X-ray crystallography images, to hypothesize and build models of the DNA molecule. They focused on creating a model that showcased how the double helix structure of DNA could explain its functionality in carrying genetic information. Their work ultimately led to the discovery of the double helix structure of DNA in 1953.

She didn't discovered the DNA. She contributed to the understanding of its structure.

DNA was first isolated by Friedrich Miescher in 1869.

Rosalind Franklin's x-ray images of DNA suggested a helical shape, specifically a double helix structure. This played a crucial role in the discovery of the structure of DNA by Watson and Crick.

In 1665, a man named Robert Hooke observed "cell-like compartments" while looking at a slide of cork. He called them "cells" due to the resemblence to monks' cells.

Erwin Chargaff was born in Austria-Hungary on August 11, 1905 and died in New York City on June 20, 2002. He was a biochemistry professor at Columbia University. Chargaff is credited with discovering information that led to the discovery of the double helix structure of DNA.

Thomas Edison was inspired to make the light bulb by a desire to find a practical and long-lasting alternative to gas lighting. He wanted to create a cost-effective and efficient way to provide light to homes and businesses. Through experimentation and innovation, Edison and his team developed the first commercially viable incandescent light bulb.

A pentose sugar (ribose or deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil).

Watson and Crick developed the double helix model to represent the structure of DNA in three dimensions. This model consists of two intertwined strands forming a twisted ladder shape, with nucleotide bases on the inside and sugar-phosphate backbones on the outside. The double helix structure of DNA allows for efficient replication and transmission of genetic information.

DNA is a double helix composed of two strands of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base. The nitrogenous bases (adenine, thymine, cytosine, and guanine) form complementary base pairs held together by hydrogen bonds.

Rosalind Franklin played a key role in discovering the structure of DNA. Using X-ray diffraction images, she provided critical data that led to the understanding of DNA's double helix structure. Her work laid the foundation for the groundbreaking discovery of the DNA molecule's structure by Watson and Crick.

Watson and Crick discovered the double helix structure of DNA in 1953, which revolutionized our understanding of genetics and inheritance. Their work laid the foundation for modern molecular biology and has had a profound impact on scientific research and medical advancements.

Francis crick and James Watson discovered the structure of DNA in 1953.

Chargaff's rule states that in DNA, the amount of adenine equals the amount of thymine, and the amount of guanine equals the amount of cytosine. This supported Watson and Crick's double helix model by suggesting complementary base pairing between adenine and thymine, and guanine and cytosine, providing a structural basis for the double helix.

Thomas Edison did not invent the light bulb, but he improved upon existing designs and made it commercially viable. He experimented with thousands of materials and designs before finding a long-lasting carbonized bamboo filament that worked well. Edison's team at his Menlo Park laboratory in New Jersey worked tirelessly to develop a practical and efficient incandescent light bulb that could be mass-produced for widespread use.
