With Expert Solutions for thousands of practice problems, you can take the guesswork out of studying and move forward with confidence. It describes the current understanding of cell biology and includes basic biochemistry, experimental methods for investigating cells, the properties common to most eukaryotic cells, the expression and transmission of genetic information, the internal organization of cells, and the behaviour of cells in multicellular organisms. Each nucleotide consists of a specific arrangement of about 35 covalently linked atoms, forming a sugar–phosphate molecule with a nitrogencontaining side group, or base, attached to it.

As we describe in Chapter 8, scientists can now rapidly read out the sequence of nucleotides in any DNA molecule and thereby determine the complete DNA sequence of any cell’s genome—the totality of its hereditary information embodied in the linear sequence of nucleo­ tides in its DNA. This fact provides compelling evidence that all living things on Earth have inherited the form of their genetic instructions, as well as how to use them, from a universal common ancestral cell. Glossary Terms Throughout the book, boldface type has been used to highlight key terms at the point in a chapter where the main discussion occurs.

Through several billion years of evolution, these sequences have been selected to give each pr All Cells Use Proteins as Catalysts Like DNA and RNA molecules, protein molecules are long unbranched polymer chains, formed by stringing together monomeric building blocks (subunits) drawn from a standard repertoire that is the same for all living cells. After exploring some of the ways that genomes change over evolutionary times, we highlight the handful of model organisms that biologists have chosen to focus on to dissect the molecular mechanisms underlying life. As always, we are also indebted to a large number of scientists whose generous help has been essential for making the text as clear, up-to-date, and accurate as possible.

The end result is two daughter DNA double helices that are identical in sequence to the parent double helix. And production manager Jane Searle adeptly managed the process of translating our raw material into the polished final product. The more than 180 animations and videos are integrated into the ebook and also available to students and instructors at digital .
