What is the molecule that caused transformation in Griffith's mouse experiment?

The molecule that caused transformation in Griffith's mouse experiment was DNA. When heat-killed S strain bacteria (which had DNA) were mixed with live R strain bacteria (which did not), the DNA from the dead S strain bacteria was able to transfer genetic information to the live R strain bacteria, making them pathogenic.


What the letters does NOT represent one of the possible bases in the DNA structure?

The letter R does not represent one of the four possible bases in DNA. The four bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).


Which scientist are cretided with the discovery that DNA is the chemical capable of transforming live R cells in mice?

The discovery that DNA is the chemical responsible for transforming live R cells in mice is credited to Frederick Griffith. In his 1928 experiments with Streptococcus pneumoniae, Griffith demonstrated that non-virulent R strain bacteria could be transformed into virulent S strain bacteria when exposed to heat-killed S strain. This transformative principle was later identified as DNA by Avery, MacLeod, and McCarty in 1944.


Does DNA replication occur at the ribosomes?

No. Chromosomes are found in the nucleus of the cell and these have sections which have codes. These codes are called genes. Ribosomes are found free in the cytoplasm or in the rough endoplasmic reticulum where they make proteins.
