Select all the statements that provide evidence that DNA is the genetic material. Check All That Apply 1. By weight, a eukaryotic chromosome contains more protein than DNA. 2. Treatment of purified DNA with a DNA-degrading enzyme destroyed the ability of S bacteria to transform R bacteria. 3. The R mutant form of S. pneumonia does not cause infection in mice. 4. Radioactively-labeled DNA remained in bacterial cells after phage T2 infection. 5. Proteins are more complex than DNA because they are composed of 20 different amino acids. Pls help asap!! I am so
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.

Why bat eukaryotic chromosome contain more protein than DNA because DNA is wrapped on histone protein this is made up of 5 subunit of protein H1, H2A, H2B H3 & H4. The complex combination of this histone protein and DNA is called chromosome.
2.. DNA degrading enzyme work on DNA and destroyed it, Due to destruction DNA does not capable to go through transcription and father translation and Protein synthesis result the bacteria does not convert into a smooth type to rough type.
