Biology
1 answer:
Wittaler [7]3 years ago
8 0

Avery's experiments showed that bacteria are transformed by “transforming principle” – DNA.

When Griffit in his experiments showed that R-strain bacteria (non-virulent) could be transformed by the heat-killed S bacteria, and become virulent, scientists assumed that there is some kind of “transforming principle” that is involved.

Avery and his colleagues cultured heat-killed S cells and tried t separate cellular components that could possibly be that “transforming principle”. Molecule of DNA gave positive result in a chemical test and also when enzymes able to degrade DNA were introduced, the transforming activity was eliminated.

Why are archaea in a different domain from bacteria apex?
mariarad [96]
The archaea are in a different domain from bacteria due to certain differences in their morphology and habitats, the Archaea are the separate domain of life in prokaryotes. For example; unlike bacteria, archaea cell walls do not contain peptidoglycan, they have different membrane lipid bonding from bacteria and eukarya.
Archaea is  considered as the different domain of life in prokaryotes, as they are the most primitive type and known as the ancient microbes found in extreme niches such as hydrothermal vents, higher salt concentration, high temperature, and pressure etc

What is the basic unit of structure and function in protists and monerans?
Alex787 [66]
I believe that the basic unit of structure and function in protists and monerans is the cell. This is because cells are basic unit of structure and function of all living things. A  cell is the smallest unit of life, it is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
