Cell Division and Genetics

Overview

This title explains what happens when cells divide. Cell division is the way in which organisms grow. Even when an organism is fully grown, some cells continue to divide to replace those that have become old or damaged. This book explores the complex relationship among chromosomes, genes, and DNA. It then examines the special form of cell division involved in reproduction, and how characteristics are passed on from one generation to another so that a pig gives birth to piglets ...

Editorial Reviews

School Library Journal
Gr 6-9-These books give excellent explanations of complex processes and terms through text, diagrams, and photographs. The attractive page design with judicious use of white space, colors, and highlighted sidebars makes the information accessible. In the first title, Snedden describes the cell cycle, reproduction, development, genes, DNA, and patterns of inheritance. The full-page genetic code table includes an explanation of how it works. The second title introduces the controversy surrounding genetic engineering. Readers learn about gene control, the benefits of bacteria, plasmids, phages, plant regeneration, gene therapy, clones, the Human Genome Project, genetically engineered plants, pharmacogenomics, and transgenic animals. The captions, highlighted in blue, offer more explanations of complex terms. More than 80 words are highlighted in bold and defined in the glossaries. Photographs taken through microscopes are amazingly clear. Richard Beatty's Genetics (RSVP, 2001) offers more biographical information on scientists, but isn't quite up to the level of these books on graphics. Students will find both of these well-written volumes useful for reports, completing homework assignments, and reviewing for tests. Teachers may want to use the DNA book as a discussion starter on the ethics of cloning.-Michael McCullough, Byron-Bergen Middle School, Bergen, NY Copyright 2003 Cahners Business Information.
