Understanding cell organization to tackle cancer

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

Cell Biology and Genetics

By: Charles K.Twesigye

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

Genetics - Second Edition

By: Karvita B. Ahluwalia...

Man’s curiosity to know about transmission of hereditary characters is as old as humanity itself. From the earliest times it had been noticed that the offspring may resemble their parents, grandparents, or other relations. Around 300 BC the great Aristotle had observed that peculiarities of hair, nails and even gait may reappear in offspring, that characters not visible in an individual may also be inherited. It appears that the existence of heredity was taken for granted. Yet, the rules which govern transmission of characters were not understood. Explanations were sought everywhere, even in the prevailing beliefs of the time such as magic,
witchcraft, gods and folklore.

Many considered heredity to be some sort of a blending process, because of which the offspring showed different ‘‘dilutions’’ of the parental characteristics. The concept of blending inheritance

Addressing Race and Genetics

By: Michael J. Rugnetta and Khusboo Desai

The human genome sequence has been fully completed for a decade now and the price of full genome sequencing is dropping precipitously. Many believe that with these developments, a new era of personalized medicine is about to hit full speed. Personalized medicine is essentially “the use of genetic susceptibility or pharmacogenetic testing to tailor an individual’s preventive care or drug therapy,” although some definitions also include the development of patient outcomes research, health information technology, and care delivery models.1 Put more simply, it means the development of medicines and therapies tailored to patients’ unique genetic traits and risks.
