DNA was came up with in 1953. James Watson and Francis Crick were the two people that proposed DNA. They said that DNA is made of 2 chains of nucleotides held together by nitrogenous bases. They are held together by hydrogen bonds.

James watson and Frincis crick said that Dna is made up of 2 chains of nucleotides held together by a nitrogenous bases. They held together by hyrogen bonds. DNA was discovered in 1953.

The concept of DNA was invented in 1953. James Watson and Francis Crick were the inventors of the concept. In thier experiement they said that the DNA was made up of two chains of nucleotides held together by nitrogeneous bases. These bases are held togeter by hydrogen bonds.

james watson invented DNA in 1953 it was always there but he though of the way to make it something that you can read and understand. now people use it for many differant things. the police can use dna so they can find out if someone was involved in a crime. there are still new things that people are thinking of all the time

In 1953, James Watson and Franics Crick published a letter in a journal that was only one page in length. Yet monumental in importance. It proposed that DNA is made of nucleotides held together by nitrogenous bases.

Francis Crick and James Watson came up with DNA in 1953. They came to the conclusion that DNA is made up of two chains of nitrogen bases

The structure of dna is the information for a life-the complete instructions for manufacturing all the proteins for an organism.

James Watson and Francis Crick came up w/ it. DNA is make like a zipper. The chains of nucleotides are held together by nitrogenous bases.

James Watson and Fraincis are the ones that came up with it and they said that it is made up of 2 chains of nucleotides and they ar held together by hydroden bonds.

dna is made from 2 chains of nucleotides held together by nitrogenous bases. it was found by james watson and fransic crick.in 1953 it was found
