Proteins are constructed in cells according to the instructions coded into DNA. Proteins are also much easier to see than the coding of DNA molecules, so there was a time where differences between proteins were detectable and differences in DNA were not detectable. As such, the logical hypothesis is that proteins are inherited and duplicated without any other source of instructions. In fact, it is DNA that is hereditary, and the variations in proteins that were observed to be hereditary previously are now understood to be artefacts from the use of the same DNA instructions.
they are more chemically complex than DNA.
In general I don't think they did, while proteins were a possibility, they were also investigating an acid (DNA) as the likely substance.
Protein
Snakes are carnivores - not omnivores ! An omnivore eats both meat protein and plant material - Snakes feed exclusively on meat protein !
Frogs get protein by eating live prey.
Protein Synthesis :), also known as TRANSLATION.
Milo runs at around 8.9% protein.
Virus :)
virus
A Virus
DNA (Deoxyribonucleic acid)
A Virus They have a protein coat to encase them

James Watson and Francis Crick
The capsid. Made of protein, and sometimes various types of proteins.
They found that all of the viral DNA and little of the protein had entered E. coli cells. Then they concluded that DNA is the hereditary molecule in viruses.
The gel like substance found inside the cell is
that DNA rather than the protein coat of a virus contains the hereditary material.
They found that all of the viral DNA and little of the protein had entered E. coli cells. Then they concluded that DNA is the hereditary molecule in viruses.
