Scientists have identified how cells know which way up they need to be. The discovery could help in the fight against cancer because in the early stages of the disease the cells become dis-organized.

Understanding DNA - Third Edition
By: Chris R Calladine, et al.
This is a book about DNA, the most central substance in the workings of all life on Earth. It is a book about the way in which DNA works at a molecular level. We have used the title Understanding DNA…because our subject has now reached the stage where many aspects of it are well enough understood for us to be able to give a clear and uncluttered presentation of the main ideas. But we shall not disguise the fact that there is still a great deal which is not known or understood.
The book can be read at two different levels. First, it can be taken as an easy-to-read textbook for undergraduate or graduate students of chemistry and biology at university. Second, it may be

MITOSIS
During the process of mitosis the parent cell containing a given number of chromosomes divides to form two daughter nuclei or cells containing the same number and kinds of chromosomes as that of the parent nucleus or cell.
MEIOSIS
Meiosis refers to the type of cellular division that normally occurs as part of sexual reproduction when the new daughter cells receive that haploid (n) number of chromosomes.
PROKARYOTE
Organism (which is often also reference to a given type of cell) that lacks the membrane-bounded nucleus
