Which statement best describes cancer cells? They grow as a single layer of cells. They cease to reproduce after 20–50 mitotic divisions. They reproduce only when needed to replace missing cells. They are not regulated by contact inhibition.

Answers

The statement which best describes cancer cells is that: D. They are not regulated by contact inhibition.

Cancer can be defined as the uncontrolled division of certain bodycells, which then invade the surrounding tissues of the body and interfere with the body's normal function.

Basically, cancer cells are caused when various body cells grow and divide more than they are required or they fail to when necessary (required).

Generally, some examples of cancer are:

  • Prostrate cancer.
  • Carcinoma.
  • Breast cancer.

The growth and division of body cells is controlled by cyclin-dependent protein kinases (Cdks) and regulated by subunits called cyclins during contact inhibition.

In conclusion, cancer cells are caused when body cells are not regulated by contact inhibition, which may be due to exposure to extremely dangerous radioactive substances such as gamma ray, uranium etc.

They are Not regulated by contact inhibition. The other 3 options are not characteristics of a cancer cell. Cancer cells have unlimited cell division, no anchorage dependent inhibition, no contact inhibition, and forms tumors - hence they don't form a single layer of cells

Answers

DNA is a molecule that controls cellular activity by directing the synthesis of proteins.

Where DNA is present?

The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.

Thus, DNA is a molecule that controls cellular activity by directing the synthesis of proteins.
