Question

In the 1950s, when watson and crick were working on their model of dna, which concepts were well accepted by the scientific community?

Answer 1

In the 1950s, Both Watson and Crick were working on the composition of DNA, that is, the molecule that comprises the hereditary information for cells. The discovery of the double-helix, and the twisted ladder composition of DNA, by Watson and Crick, signified a landmark in the field of science and paved the path for the origination of modern molecular biology.

However, when Watson and Crick were working on DNA model, some of the concepts were well accepted by the scientific community like the chromosomes are formed of nucleic acid and protein, chromosomes are found in the nucleus, and genes are located on the chromosomes.

Answer 2

Watson and Crick describe structure of DNA 1953 Photo: Model of DNA molecule In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases. In 1950, biochemist Erwin Chargaff found that the arrangement of nitrogen bases in DNA varied widely, but the amount of certain bases always occurred in a one-to-one ratio.
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.
Watson and Crick showed that each strand of the DNA molecule was a template for the other.
