Describe the results of three experiments that to show dna is the genetic material

The three experiments are:

Griffith performed an experiment by which he observed that harmless R strain of the bacteria transformed into harmful S strain when mixed with heat-killed S strain.

He concluded that the "transforming principle" from the heat-killed S strain bacteria transformed the R strain.

They identified that the nature of the transforming principle mentioned by Griffith.

They used digestive enzymes such as proteases, RNase, and DNase.

They conclude that the transforming principle was DNA in nature.

They used radioactive sulfur to label proteins and radioactive phosphorus to label DNA in the bacteriophage.

The infected bacteria were blended and centrifuged.  

The radioactive phosphorus, that is, DNA was found inside the cell whereas the radioactive sulfur, that is, proteins were found outside the cell.

It also proved that the genetic material was DNA, not protein or RNA.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.  

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
