Early observations of a cultured cell line indicated that the cells did not exhibit either density-dependent inhibition or anchorage dependence. what do these observations suggest about this cell line? the cells are unable to form spindle microtubules. the cells follow an altered series of cell cycle phases. the cells show characteristics of tumors. the cells have nonfunctional mpf.

The cells show characteristics of tumors.  

Tumor cells have the ability to grow and proliferate in absence of adhesion or anchoring. This is particularly helpful during metastasis when a cancer cell travels through the bloodstream to another location.

A cancerous cell has a number of mutations that regulate cell division. In addition, they exhibit impairment in DNA repair system. Therefore, cancer cell divided fast. Since the DNA repair system is nonfictional, the cells do not pause division to repair the mutation.
