nucleic acid nucleic acid. A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells.This compound was neither a protein nor lipid nor a carbohydrate; therefore, it was a novel type of biological molecule.ucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a new compound from the nuclei of white blood cells.

- Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.

What Is Biochemistry? - Definition, History & Topics Biochemistry had been studied and the word possibly used within the scientific community longer than 1903 in projects such as alcoholic fermentation, discovered by Eduard Buchner in 1896. This study is a prime example of the chemical processes that occur to either create a new compound or allow an organism to survive.

Who discovered cells? Quick Answer. Cells were discovered in 1665 by Robert Hooke, whose findings were published in the book Micrographia.. The second scientist to observe cells was Anton van Leeuwenhoek. In his work, he discovered bacteria, as well as sperm and egg cells, which disproved the theory of spontaneous generation. Hooke later confirmed van Leeuwenhoek`s findings.

Periodic table history In 1863 English chemist John Newlands divided the then discovered 56 elements into 11 groups, based on characteristics. In 1869 Russian chemist Dimitri Mendeleev started the development of the periodic table, arranging chemical elements by atomic mass. He predicted the discovery of other elements, and left spaces open in his periodic table for them. In 1886 French physicist Antoine Bequerel first discovered radioactivity. In 1897 English physicist J. J. Thomson first discovered electrons; small negatively charged particles in an atom.

Watson and Crick discover chemical structure of DNA Though DNA–short for deoxyribonucleic acid–was discovered in 1869, its crucial role in determining genetic inheritance wasn’t demonstrated until 1943. In the early 1950s, Watson and Crick were only two of many scientists working on figuring out the structure of DNA.

The Secret Pulse of Time At the turn of the century, there was little known about atoms except that they contained electrons. J. J. Thompson discovered the electron in 1897, and there was considerable speculation about where these negatively charged particles existed in nature. Matter is electrically neutral; some positive charge must balance the charge of the electron.

- On this day in 1953, Cambridge University scientists James D. Watson and Frances H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes.he discovery of DNA by James Watson and Frances Crick being a major one for the scientific community. Not only was DNA discovered on this day, but the Republican Party was founded in Wisconsin.

- Subatomic Particles The rather steady increase of atomic masses through the periodic table was explained when physicists managed to split atoms into three component particles. The exploration of atomic structure began in 1911, when Ernest Rutherford, a New Zealander who worked in Canada and England, discovered that atoms had a dense central nucleus that contained positively charged particles, which he named protons.

- Watson and Crick took a crucial conceptual step, suggesting the molecule was made of two chains of nucleotides, each in a helix as Franklin had found, but one going up and the other going down. Crick had just learned of Chargaff's findings about base pairs in the summer of 1952.

- 1 The electron was discovered in 1897 by the English physicist J.J. Thomson during investigations of cathode rays. His discovery of electrons, which he initially called corpuscles, played a pivotal role in revolutionizing knowledge of atomic structure.

- Molecules aren't only found in biology. Sulfur is a molecule that is found naturally in the earth. It contains a group of sulfur atoms connected in a ring, like a daisy chain.Carbon nanotubes and fullerenes are carbon-containing molecules that can be found in meteorites as well as some kinds of steel.norganic chemistry is just the rest of chemistry. It is the part that is not principally based on carbon. It turns out that there is a lot of important inorganic chemistry in biology, as well. Frequently, metal ions play crucial roles in There are important applications of inorganic chemistry, too.
