Option A, C, D and E are applied.

<h3><u>Explanation:</u></h3>

Cancer is a disease in humans where there's uncontrolled cell division which doesn't stop in absence of a inhibition.

Cancer cells do show different characteristics which are different from the normal cells. Firstly, they doesn't show contact inhibition. They don't stop dividing inspite of contact with the surrounding cell from each side. This results in the Tumour or nodule formation.

Secondly, they secrete factors which supports growth of new blood vessels around the tumours. They are called angiogenesis promoting factors.

Thirdly, they divide very rapidly, much higher than normal cells. So the biopsy slide with frequent mitotic figures are very common. And these cells lack telomerase, which leads them to live much longer than what is expected lifespan of a normal cell. They don't even need a growth signal for their division.

Yes, Avery, Mc Leod and Mc Carty do thought that genes may be involved in the transformation of non virulent rough Strains of <em>Diplococcus pneumoniae</em> to harmful smooth strained bacteria

<h3><u>Explanation:</u></h3>

Avery was a Canadian medical researcher who along with other two well known scientists of the contemporary time went for an experiment where he took two strains of bacteria Diplococcus pneumoniae - one is rough and nonvirulent and another is smooth and virulent. For a control run, he injected both the bacteria in separate mice and the expected result was there. Now as he injected heat killed smooth bacteria, the mice survived. But as he injected heat killed smooth bacteria with rough bacteria, although there was no organism which can kill the mice the mice died. And autopsy revealed the presence of live smooth bacteria in the lungs.

Thus they suspected something have gone from the dead smooth bacteria into the non virulent rough bacteria which lead to transformation of the rough bacteria to smooth ones. Thus, the experiment was carried on, which suspected role of genes in this transformation.
