The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.
While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration occurs in the cytoplasm and mitochondria, respectively, of the cell.
<h3>What is cellular respiration?</h3>
The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. All kinds of cellular operations are then powered by the energy that is stored in ATP molecules.
There are three types of cellular respiration
1) Anaerobic respiration happens when there is no oxygen present.
2) Aerobic respiration occurs when there is oxygen present.
