What did Pauling discover about DNA?
Answer and Explanation: Linus Pauling is known as the “Father of Molecular Biology”. In the 1950s he discovered the spiral structure of proteins by using X-ray crystallography. Pauling’s discovery of protein helical structure lead to the discovery of DNA’s double-helical structure in 1953.
Who discovered the vitamin C?
Albert Szent-Györgyi
Albert Szent-Györgyi, a Hungarian biochemist, discovered vitamin C and rutin (vitamin P). The role of these vitamins in the body and their application to dermatology is vast. For the discovery of vitamin C and the description of oxidation, Albert Szent-Györgyi received a Nobel Prize in medicine in 1937.
What is Pauling experiment?
Pauling later performed a technique comparing proteins among people with sickle cell, without sickle cell and carrying a gene for sickle cell (Bloom, 1995). He found that the hemoglobin of those with sickle cell differed from those without it. The carriers of sickle cell had both types of hemoglobin, (Bloom, 1995).
What did Pauling and Corey discover about DNA *?
Pauling and Corey state that when scientists observed DNA under an electron microscope, they saw fibers that appeared to have a circular cross section, characteristic of a helical structure or a spiral staircase.
Who is the father of vitamin?
Casimir Funk
The history of the discovery of vitamins is the history of their deficiency disorders. Their discoverer was Casimir Funk, who is considered the ‘father of vitamin therapy’.
What is the law of electroneutrality?
The law of electroneutrality states that in any single ionic solution a sum of negative electrical charges attracts an equal sum of positive electrical charges.
How does the law of electroneutrality affect stoichiometries?
This law of electroneutrality results in the formation of very specific stoichiometries—that is, specific ratios of cations to anions that maintain a net balance between positive and negative charge. In fact, anions are known to pack around cations, and cations around anions, in order to eliminate…
What is the law of electroneutrality of KCl?
The law of electroneutrality states that in any single ionic solution a sum of negative electrical charges attracts an equal sum of positive electrical charges. If a solution of KCl is divided into two parts by a membrane that is permeable to both ions, then the…
What led Pauling to conclude that the electroneutrality principle is true?
The electroneutrality principle led Pauling to the conclusion that charge transfer from O to Si must occur using d orbitals forming a π-bond and he calculated that this π-bonding accounted for the shortening of the Si-O bond.
