DNA Replication Deoxyribonucleic acid (DNA) contains the genetic instructions for the biological development of a cellular form of life including some viruses. DNA is an antiparallel double helix molecule with sugar-phosphate backbone on the outer side and nitrogen bases in the inner side. The bases are paired specifically‚ also known as complementary pairing‚ Adenine (A) with Thymine (T)‚ and Guanine (G) with Cytosine (C) by two and three hydrogen bonds‚ respectively. DNA is a long polymer

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

Biotechnology Regulations and Ethics FDA Regulation of Probiotics One of the most significant implications of the Human microbiome project (HMP) is the expansion of number of probiotic products available on the commercial market. As‚ it is new area of study‚ new claims are being made about the role and the value of probiotics in promoting human health and well-being. However there is some uncertainty about the how these products should be regulated. The Goal of this paper is to discuss the current

Evolution by natural selection is slow but can be observed in certain situations. How to spot evolution in real time: Artificial selection – manipulation by humans such as breeding dogs or growing corn. Repro-rate – rate of reproduction. Stochastic Event: unexpected disaster like a volcano eruption or tornado. (Research geological time) LIVING THINGS: Biology – Study of living things. Living things – all the organisms descended from a single-celled ancestor. * Characteristics:

CHAPTER 1 PRODUCTION 236250 TONNES PER YEAR OF ACETONE 1.0 INTRODUCTION Acetone is a clear‚ colorless‚ volatile liquid with sweer odor. It is both the simples aliphatic ketone and the most commercially important. It has a distinctive fruity or mint-like odor and a pungent taste. It is also found naturally in plants‚ tress‚ volcanic gases‚ and forest fires and as a by product of the breakdown of body fat. Nearly all world production of acetone is via cumene peroxidation‚ as a coproduct with

Human Digestive System The digestive tract is a series of hollow organs through which food passes: mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine. Each portion is specialized for one or more aspect of the three major functions of the digestive system the secretion‚ digestion‚ and absorption. Accessory organs such as salivary glands‚ liver‚ gallbladder and pancreas have duct that lead into the digestive tract and thus support digestive function. Digestion is defined as the mechanical
