Deoxyribonucleic acid, better known as DNA, is located in the nucleus of all living cells. DNA dictates which creatures walk, fly, or bore through the soil. Each DNA strand is made up of four nucleotides or "building blocks": adenine,...

At its most fundamental level, molecular biology is the study of biological molecules and the molecular basis of structure and function in living organisms. Molecular biology is an interdisciplinary approach to understanding biological functions and...

Molecular biology is the field of study concerned with the structural and functional properties of biological systems. Specifically, it attempts to understand the function of molecules within a living system and how they interact. It includes such...

Biologists study life on many different levels. For example, a cellular biologist is concerned with the most basic unit of life, the single cell, whereas an evolutionary biologist may investigate the origin and genealogical history of a particular...

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between...

Molecular Biology of the Brain, edited by S.J. Higgins. Princeton, NJ: Princeton University Press, 1999. 196 pp. $32.50. The brain is one of the most complicated of all evolutionary adaptations, and is probably the most intriguing. How the complexities of human thought, language,...

1. INTRODUCTION Molecular biology is one of the most important scientific frontiers in the second half of the twentieth century. During this period, the basic principles of how genetic information is encoded in the DNA and how this information is used to...

Attacking several tons of woolly mammoth with stone-tipped spears must have taken extraordinary courage _ and ancient people left paintings to prove they did it. Now, scientists are approaching mammoths in a different way, extracting DNA from their dense coats in an effort to learn...

Scientists say a new bacteria species discovered in Yellowstone's thermal pools could improve the use of bacteria to produce ethanol.Researchers found the bacteria in Octopus and Mushroom springs as well as in Green Finger Pool. The bacteria thrive in hot water, growing best between 120...
