Ostwald T. Avery's experiment was an extension of the works of Griffith's. Griffith's experiment using virulent and avirulent Streptococcus pneumoniae (which had different colony characteristics) proved that it was possible for the heat killed virulent Streptococcus pneumoniae to pass on the genetic information for formation of smooth colonies to avirulent strains. Avery, Mc Leod and Mc Carty conclusively found out that the genetic material responsible for transfer of characteristics between the strains was DNA. This was achieved by incubating the cell lysate of virulent Streptococcus with proteases, RNAses and DNAses separately before mixing it with avirulent strains. It was found that only when the lysate was incubated with DNAses did the transfer of smooth colony formation characteristic from the virulent strain to the avirulent strain fail to occur.
He discovered that DNA contains a double helix spiral
Avery's theory provided evidence for knowing that DNA contains the instructions for the making of the capsule in the Sstrain of S. pneumoniate.
Yes
At the time when this theory was a-brewing, it was difficult to provide conclusive data and evidence.

The cell theory states:Cells are the basic units of structure and function in living things.All living things are composed of cells.All cells are produced from other cells.
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors

Averys of Bristol, are fine wine merchants since 1793, sell fine wine to anybody in the world. They provide customers with the finest of their high-quality wine.

plate tectonics, which explains the movement of Earth's outer shell. Fossil remains on separate continents that were once part of the same landmass suggest that continents were once connected and have since drifted apart. The shape of continents also fits together like a puzzle, supporting the idea of continental drift and plate tectonics.

In physics, experiments are mostly used to provide proof of a theory. For example, when a theory predicts a particular relation between an object, its placement, and the time it takes to fall to the floor, a series of experiments can be conducted to provide evidence for the theory, or to dismiss it.
Alfred Wegner developed the theory of plate tectonics, not a theory of a shrinking Earth. The Earth is not shrinking and no scientific theory has ever proposed that it is.

"Evidence". There's no special term to distinguish evidence supporting one theory in science from evidence supporting any other theory in science.
