Describe the evidence that showed that the genetic material of bacteriophage viruses was DNA (This was the Hershey-Chase experiment using the radioactive sulfur and phosphorus.).

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
