DNA was discovered by a Swiss scientist, Friedrich Miescher, in 1869.
In 1953 James Watson and Francis Crick proposed the double-helix structure for the molecule, and by 1966 the genetic code (i.e. which amino acids were coded for by which sequences of DNA bases, and what the remaining codons "meant", ) had been completely worked out.
__________________________________________________________________________
While examining the DNA molecule, Watson and Crick (1953), proposed a satisfactory model for the arrangement of these constituents. For this important contribution to science they were given the 1962 Nobel Prize. They hypothesized from X-ray analysis of the molecule that DNA consists of two strands, twisted in a spiral (or helix) shape. This shape resembles a twisted ladder with rungs between the two uprights. The "uprights" of this ladder are made entirely of alternating phosphate and sugar molecules. The rungs are composed only of the nitrogen bases, which are attached to the sugar. The phosphate-sugar-base is called a nucleotide. The base of the nucleotide from one "upright" of the ladder is paired with and bonded to the base of the nucleotide from the other side of the ladder, completing the rung between the two uprights. A nucleotide having adenine is always cross-paired with thymine, and one with cytosine is always bonded to guanine.

What year was DNA discovered?
DNA was discovered in 1869 by Friedrich Miescher, a Swiss biologist who isolated it from the nuclei of white blood cells. However, the significance of DNA as the carrier of genetic information was not fully understood until the mid-20th century, when the structure of the DNA molecule was elucidated by James Watson and Francis Crick in 1953.
What did DNA stand for when it was first discovered?
DNA stands for deoxyribonucleic acid, which was first discovered in the 1860s by Friedrich Miescher.
When was DNA discovered in the 1950's?
DNA was discovered as the genetic material in the 1950s by James Watson and Francis Crick in 1953. They proposed the double helix structure of DNA, which revolutionized the field of genetics and laid the foundation for modern molecular biology.
Who discovered the amount of adenine in DNA is always equal the amount of thymine?
Erwin Chargaff discovered the rule that the amount of adenine in DNA is always equal to the amount of thymine. This finding was a key breakthrough in understanding the base pairing rules in DNA.
What did wilkins and franklin discover about DNA?
Wilkins and Franklin discovered the structure of DNA using X-ray diffraction studies, which showed that DNA has a helical structure with a repeating pattern. Their work provided crucial insight into the double helix structure of DNA, paving the way for Watson and Crick to propose the famous model of DNA in 1953.

What did DNA stand for when it was first discovered?
DNA stands for deoxyribonucleic acid, which was first discovered in the 1860s by Friedrich Miescher.
Who discovered helicase and what year?
Helicase was discovered by James M. Berger and Stephen J. Kowalczykowski in 1995. They identified the role of helicase in DNA replication by studying its function in unwinding the double helix structure of DNA.
What year did rosalind Franklin discover DNA?
Rosalind Franklin did not discover DNA. DNA was discovered long before she photographed the images via X-ray crystallography. With the help of these images, Watson and Crick were able to figure out the structure of the nucleic acid in 1953. Watson and Crick did not discover DNA either; they developed the concept of the "double helix," which was accepted as the structure of DNA.
