Prior to the Avery, MacLeod, and McCarty experiment, what features of cells and chromosomes were already known that could have been interpreted as evidence that DNA is an important constituent of the genetic material?

موثّق

Prior to Avery, MacLeod, and McCarty experiment, it was found that chromosomes found in nucleus of cells exhibit splitting behavior, which allowed daughter cells to receive complement chromosomes. The constant number of chromosomes found in cells of same species was another finding, which suggests that chromosome could potentially be genetic material.
Later on, deoxyribose nucleic acid (DNA), and protein was found to be constituents of chromosome. While the amount of proteins found between cells varied, the amount of DNA found between cells of same species remained constant. Such finding supports the notion that DNA is an important constituent of genetic material.
