A research team began a study of a cultured cell line. Their preliminary observations showedthem that the cell line did not exhibit either density-dependent inhibition or anchoragedependence. What could they conclude right away?

A) The cells originated in the nervous system.
B) The cells are unable to form spindle microtubules.
C) They have altered series of cell cycle phases.
D) The cells show characteristics of tumors. E) They were originally derived from an elderly organism.

D)

Explanation:

Based on the scenario being described within the question it can be said that they can conclude right away that the cells show characteristics of tumors. This is because cancer cells do not exhibit these characteristics which is what allows them to continuously reproduce without anything stopping them, which in term cause tumors.

satellites are frequently used to make observations of the orbit on earth

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
