Cell division is the basis of life itself; it is how animals grow and reproduce. When cells divide, two daughter cells are produced from one mother cell. Each new cell has exactly the same genetic material (DNA) as the cell that produced it. Cellular...

Cell division is the process by which an organism grows or replaces damaged tissue. The growth of a fertilized embryo is accomplished through the division and differentiation of cells, and while some cells, such as skin cells, divide almost...

CELL reproduction occurs in two different ways: MITOSIS and MEIOSIS. Each involves the creation of new cells, but with one critical difference: mitotic cell division produces cells with identical DNA, but meiotic does not—it involves the fusion...

Cell division is the process where a single living cell splits to become two or more distinct new cells. All cells divide at some point in their lives. Cell division occurs in single-celled organisms like bacteria, in which it is the major form of...

Cell division is a process by which a cell, called the parent cell, divides into two cells, called daughter cells. Cell division is usually a small segment of a larger cell cycle. In meiosis however, a cell is permanently transformed and cannot divide...

PRESIDENT BUSH is losing the debate over embryonic stem cell research, so he is casting his opposition as a defense of a baby's right to live. But primitive embryos, from which stem cells would be gathered, do not have an infant's moral claim to...

To the Editor: We respectfully take issue with an article in your May issue ("Beginning the Transformation"), which inaccurately represented competing fuel cell technologies. The authors apparently decided to tell only one side of the fuel cell story and inaccurately concluded that so-called...

United Technologies Corp., which manufacturers heating and ventilating equipment as well as jet engines, on Wednesday reported a 20 percent increase in profit for the third quarter, crediting strength in all its businesses except Carrier, which is pressed by the deteriorating housing market.Net income in...

Like UV rays and diesel exhaust fumes, working the graveyard shift will soon be listed as a "probable" cause of cancer.It is a surprising step validating a concept once considered wacky. And it is based on research that finds higher rates of breast and prostate...

Examines how cells reproduce. Describes the ability to generate whole organisms from single cells, or small groups of cells. Describes how this is becoming important in biotechnology and genetic modification.

Essay describes cell division and how it helps keep us alive.
