Question

Describe two properties of a transformed human cell vs. a normal human cell and how these properties can lead to increased tumor cell growth.

Answer 1

Normal cells have a shape of normal pattern and you can find some irregularity.
When you perform to prepare a normal cell, when a cell grows and when cell touches then the growth stops by contact inhibition. Transform cells (Cancer or Tumor cells) have a shape that is irregular and in the nucleus it has multiple nuclei that cause it to be abnormal .
In abnormal cells there is no contact inhibition and the cells grow multiple layer which leads to tumor or cancer cell.
Healthy cell does not turn into a cancer cell overnight. Its behaviour gradually changes, a result of damage to between three and seven of the hundreds of genes that control cell growth, division and life span. First, the cell starts to grow and multiply. Over time, more changes may take place.
