Question

Some strains of cancer cells are used quite often in laboratories because they are considered immortal. What unique features of cancer cells make them immortal? A. They are have a limitless growth potential, in part due to their ability to maintain telomere length, and in culture will continue to divide indefinitely B. Cancer cells do not require access to nutrients or oxygen, so they can grow indefinitely C. They are resistant to mutation and therefore never die D. They are anchorage independent and never need a surface to grow on E. The DNA in cancer cell is not assembled in chromosomes and has no telomeres, which are used as a measure of the "life time" of a cell, so it will never age and divide indefinitely

Answer 1

Answer:

A. They are have a limitless growth potential, in part due to their ability to maintain telomere length, and in culture will continue to divide indefinitely.

Explanation:

Unlike normal cells, telomeres shorten in every cell division until eventually they become too short to protect the chromosomes and the cell dies. Cancer cells reverse the telomeres shortening, and instead, they  lengthen  them, thus they become inmortal.
