Okay smartie pants, Who "discovered" DNA?

Answer 1

Well, at least you don’t want to know a lot! We have split your questions into four separate parts (look for the other questions in our archived list). The first question will be answered here.



Who discovered DNA?



This is a tough question because it is hard to know what people mean by DNA. Do they mean genes, or the substance DNA or chromosomes or the structure of DNA or…



Here is a brief timeline of some discoveries about DNA:



1856-1865 Gregor Mendel founds genetics.



1869 Johann Friedrich Miescher discovers a weakly acidic substance in human nuclei he calls nuclein. It is later

called DNA.



1882 Walther Fleming discovers chromosomes.



1902-1903 Walter Stanborough Sutton uses grasshoppers to discover that chromosomes have genes.



1924 Chromosomes are shown to be made of protein and DNA.



1928 Franklin Griffith figures out that genetic information can be transferred from heat-killed bacteria to live ones.



1944 Oswald Avery figures out that Griffith’s substance was DNA.



1949 Edwin Chargaff figures out that no matter the species, the amount of adenine (A) equals the amount of thymine (T) and the amount of guanine (G) equals the amount of cytosine (C).



1953 Francis Crick, James Watson and Rosalind Franklin discover the double helix structure of DNA.



1961 Francis Crick and Sidney Bremmer figure out that three bases (a codon) are needed to code for an amino acid

Answer 2

Watson and Crick determined the structure first. The discovery was aided by the x-ray work of Rosalind Franklin (without her knowledge). Contrary to popular revisionist history Rosalind Franklin did not discover the structure, although she was probably on the correct path. She died before the Nobel Prize for the work was awarder. She almost certainly would have share the award with Watson and Crick as hers was the experimental evidence that proved their model. What won Watson and Crick international acclaim, was not only the structure but that they realized the structure allows for relatively easy DNA replication. While I think the above is what you are getting at, the actual discoverer of DNA was Friedrich Miescher in the mid 1800s.



As an interesting side note, Rosalind Franklin herself never thought that her work was stolen and remained friends with Watson and Crick until her death

Answer 4

Ribonucleic acid (RNA) is a nucleic acid polymer consisting of nucleotide monomers. RNA nucleotides contain ribose rings and uracil unlike deoxyribonucleic acid (DNA), which contains deoxyribose and thymine. It is transcribed from DNA by enzymes called RNA polymerases and further processed by other enzymes. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins. History Nucleic acids were discovered in 1869 by Johann Friedrich Miescher (1844-1895), who called the material 'nuclein' since it was found in the nucleus. It was later discovered that prokaryotic cells, which do not have a nucleus, also contain nucleic acids. The role of RNA in protein synthesis had been suspected since 1939, based on experiments carried out by Torbjörn Caspersson, Jean Brachet and Jack Schultz. The sequence of the 77 nucleotides of a yeast tRNA was found by Robert W. Holley in 1964, winning Holley the 1968 Nobel Prize for Medicine. SMILE Good Luck and God Bless have a great day

Answer 5

When I first learned about the structure of DNA in an undergraduate genetics class, my instructor-a British scientist and feminist-hammered one point into our heads: James Watson and Francis Crick did not discover the famous double helix alone. The x-ray photograph that led to their breakthrough came from the lab of a little known King's College scientist named Rosalind Franklin. No one gave her credit for her work, my instructor said, so Franklin died in scientific obscurity.

Answer 6

Deoxyribonucleic acid was known to exist as early as the mid-19th century. However, it was only in the early 20th century that researchers began suggesting that it might store genetic information. This was only accepted after the structure of DNA was discovered by James D. Watson and Francis Crick in their 1953 Nature publication.

Answer 7

James Watson and Francis Crick identified the STRUCTURE of DNA. DNA itself was discovered almost 150 years ago. Friedrich Miescher isolated "nuclein" (crude DNA) from salmon sperm in 1869. The name "nucleic acid" was coined in 1889 by his student, Richard Altmann.

Answer 8

DNA's accepted model was given by Watson and Crick.. actual thought on inheritence and the conceptualization of pangenes although incorrect.. was present much before Watson and Crick.. DNA was all in all discovered by many scientists and its discovery is not acclaimed to one person.

Answer 9

Donald Newton Alexander. Hence DNA.

Answer 10

This one is too easy APG. DNA was named after the first thing out of the mouth of the scientist who discovered it when he said: "Done gonna Nail your ***!" .....everyone seemed to like what he said and it was shortened to DNA.



To answer your question more specifically it was discovered by Joe Friday from Dragnet.

Answer 11

Watson and Crick are typically credited for the discovery of DNA but Rosalind Franklin's work enabled them and was fundamental to their discovery.

Answer 12

D was discovered by Alexander the Great

N was discovered by Pliny the Elder

A was discovered by Sophocles

Answer 13

Friederich Miescher? http://www.newton.dep.anl.gov/askasci/bio99/bio99283.htm

Answer 14

Watson & Crick

Answer 15

If you read all the above answers you will be greatly enlightened about DNA and its discovery.

Answer 16

I think there is little to be added to the great answers above.

Answer 17

i read it when i was in school. but now only can remember DNA is 'Dioxy Nucleic Acid'. formula of life....forgot the brain boy's name.

Answer 18

a scientist

Answer 19

wastion and crick

Answer 20

I don't know, who?
