Despite the fact that their numerous abnormalities would ordinarily make them great targets for apoptosis, cancer cells even avoid programmed cell death. As cancer progresses, cells cross the borders of healthy tissue and metastasis (spread) to other locations throughout the body.
Cancer cells:
- First and foremost, cancer is a complex illness, meaning that several faulty genes are implicated. It is not the case that one faulty gene causes a cell to develop into a malignant cell.
- Metastasis refers to the spread of a cancer.
- Uncontrolled growth is a given if there is a constitutively active RTK growth factor. However, the cell has additional defense systems to prevent such unchecked proliferation. If nothing is done, the cell will undergo apoptosis and perish. The development of cancer would not exist.
Some of the typical characteristics of cancer cells include -
- Because they are anchorage independent, cancer cells can grow in both semi-solid and suspension mediums.
- Its proliferation is unaffected by contact with neighboring cells, or contact inhibition.
- Layers of cancerous cells are formed.
- Cancerous cells have a variety of shapes.
- Telomerase is expressed by tumor cells.
- They do not go through apoptosis, have damaged cell cycle regulatory genes, and proliferate uncontrollably.
- For them to grow, angiogenesis is necessary.

Answer:
A transcription factor
Explanation:
In order for transcription to begin in eukaryotes, not only must RNA polymerase be attached to the double strand of DNA, but several transcription factors must also be binded. Without them the RNA polymerase machinery will not start.
In example GTF's (General transcription factors), also known as basal transcriptional factors, are protein factors that binds into the promoter on DNA to activate transcription. The basic transcriptional apparatus that first bind to the promoter is RNA polymerase + GTFs +a multi-protein complex.
