Glossary - Cellbiology
1 Glossary - Cellbiology Blotting: (Blot Analysis) Widely used biochemical technique for detecting the presence of specific macromolecules (proteins, mRNAs, or DNA sequences) in a mixture. A sample first is separated on an agarose or polyacrylamide gel usually under denaturing conditions; the separated components are transferred (blotting) to a nitrocellulose sheet, which is exposed to a radiolabeled molecule that specifically binds to the macromolecule of interest, and then subjected to autoradiography. Northern B.: mRNAs are detected with a complementary DNA; Southern B.: DNA restriction fragments are detected with complementary nucleotide sequences; Western B.: Proteins are detected by specific antibodies. Cell: The fundamental unit of living organisms. Cells are bounded by a lipid-containing plasma membrane, containing the central nucleus, and the cytoplasm. Cells are generally capable of independent reproduction. More complex cells like Eukaryotes have various compartments (organelles) where special tasks essential for the survival of the cell take place. Cytoplasm: Viscous contents of a cell that are contained within the plasma membrane but, in eukaryotic cells, outside the nucleus. The part of the cytoplasm not contained in any organelle is called the Cytosol. Cytoskeleton: (Gk. ) Three dimensional network of fibrous elements, allowing precisely regulated movements of cell parts, transport organelles, and help to maintain a cell’s shape. • Actin filament: (Microfilaments) Ubiquitous eukaryotic cytoskeletal proteins (one end is attached to the cell-cortex) of two “twisted“ actin monomers; are important in the structural support and movement of cells. Each actin filament (F-actin) consists of two strands of globular subunits (G-Actin) wrapped around each other to form a polarized unit (high ionic cytoplasm lead to the formation of AF, whereas low ion-concentration disassembles AF).

This lecture note has been prepared with the primary aim of alleviating the problems encountered in the teaching of Medical Applied Genetics and Molecular Biology course and in minimizing discrepancies prevailing among the different teaching and training health institutions. It can also be used in teaching any introductory course on medical Applied Genetics and Molecular Biology and as a reference material. This lecture note is specifically designed for medical laboratory technologists, and includes only those areas of molecular cell biology and Applied Genetics relevant to degree-level understanding of modern laboratory technology. Since genetics is prerequisite course to molecular biology, the lecture note starts with Genetics i followed by Molecular Biology. It provides students with molecular background to enable them to understand and critically analyze recent advances in laboratory sciences. Finally, it contains a glossary, which summarizes important terminologies used in the text. Each chapter begins by specific learning objectives and at the end of each chapter review questions are also included.

NIELSEN AND TERJE TRAAVIK 1 THE NORWEGIAN INSTITUTE OF GENE ECOLOGY (GENØK), TROMSØ, NORWAY 2 DEPARTMENT OF PHARMACY, UNIVERSITY OF TROMSØ, NORWAY 3 DEPARTMENT OF MICROBIOLOGY AND VIROLOGY, UNIVERSITY OF TROMSØ, NORWAY Molecular biology is the study of biology at a molecular level, with the aim of understanding the interactions between the various systems of a cell, including the interrelationship and regulation of DNA, RNA and protein synthesis. In general terms, DNA (deoxyribonucleic acid) is the basic genetic information macromolecule of the cell. It provides the rudimentary instructions for all kinds of biochemical functions, from making proteins to regulatory functions. DNA is found in every cell and every cell type and organism, from single-celled organisms (prokaryotes, e.g. bacteria), to larger multicellular organisms (eukaryotes, e.g. seaweeds, fungi, plant, animals) that can have many different cell and tissue types.1 DNA contains the genetic ‘code’ of information that makes each species unique. Smaller variations in the DNA can lead to minor differences among individuals of the same species. The combination of specific DNA composition, epigenetic changes (see Chapter 8) and environmental influences determine an organism’s appearance and development. In this book, we discuss how the main carrier of heritable information (DNA) and the environment interact, with particular emphasis on how genetic engineering may intentionally or unintentionally affect this interaction. This chapter focuses on DNA, RNA and the concept of genes. It is structured as follows: 1.

PDF (Chapter 1
Chapter 1 Introduction 24 DNA Structure and Function Deoxyribonucleic acid (DNA) is a biological macromolecule that contains genetic information encoding for the entire structure and function of all known organisms. Various biological characteristics are accounted for by individual genes made up of specific sequences of DNA that together provide a blueprint for life, the full set of which is called a genome. DNA’s primary structure consists of a backbone of alternating 2-deoxyribose sugar units and phosphate residues, which are joined by phosphodiester bonds at the 3’ and 5’ positions of the sugar. Attached to each sugar at the 1’ position is one of four nucleobases: adenine (A), cytosine (C), guanine (G), or thymine (T). As it typically exists in nature, double-stranded DNA (dsDNA) contains two antiparallel strands of DNA in a double helix, forming a series of specific hydrogen bonding interactions between complementary nucleobases: A and T are specific for each other, as are C and G.

Abiogenic Origin of Life: a Theory in Crisis
Abiogenic Origin of Life: A Theory in Crisis 2005 Arthur V. Chadwick, Ph.D. Professor of Geology and Biology Southwestern Adventist College Keene, TX 76059 U.S.A. Origin of Life Research as Science : All phenomena are essentially unique and irreproducible. It is the aim of the scientific method to seek to relate effect (observation) to cause through attempting to reproduce the effect by recreating the conditions under which it previously occurred. The more complex the phenomenon, the greater the difficulty encountered by scientists in their investigation of it. In the case of the scientific investigation of the cause of the origin of life, we have two difficulties: the conditions under which it occurred are unknown, and presumably unknowable with certainty, and the phenomenon (life) is so complex we do not even understand its essential properties. Thus, at the outset, there is a condition of "unknowableness" about the origin of life quite different from that associated with most scientific investigations. Since the methods of science and the normal rigors of scientific investigation are handicapped, one should be more willing to give serious consideration to information from any source that might contribute to our understanding of origins, in particular to the hypothesis that life was created by an infinitely superior Being. If a careful scientific analysis leads us to conclude that the proposed mechanisms of spontaneous origin could not have produced a living cell, and in fact that no conceivable natural process could have resulted in the spontaneous origin of life, the alternative hypothesis of Creation becomes the more attractive. If, on the other hand, we find the proposed mechanisms to be plausible, we must be aware that the methods of science can never answer with certainty the question of origin.
