Glass* ([email protected]), Nina Alperovich, Nacyra Assad-Garcia, Shibu Yooseph, Mahir Maruf, Carole Lartigue, Cynthia Pfannkoch, Clyde A. Hutchison III, Hamilton O. Smith, and J. Craig Venter J. Craig Venter Institute, Rockville, MD The Venter Institute aspires to make bacteria with specific metabolic capabilities encoded by artificial genomes. To achieve this we must develop technologies and strategies for creating bacterial cells from constituent parts of either biological or synthetic origin. Determining the minimal gene set needed for a functioning bacterial genome in a defined laboratory environment is a necessary step towards our goal. For our initial rationally designed cell we plan to synthesize a genome based on a mycoplasma blueprint (mycoplasma being the common name for the class Mollicutes). We chose this bacterial taxon because its members already have small, near minimal genomes that encode limited metabolic capacity and complexity. We took two approaches to determine what genes would need to be included in a truly minimal synthetic chromosome of a planned Mycoplasma laboratorium: determination of all the non-essential genes through random transposon mutagenesis of model mycoplasma species, Mycoplasma genitalium, and comparative genomics of a set of 15 mycoplasma genomes in order to identify genes common to all members of the taxon. Global transposon mutagenesis has been used to predict the essential gene set for a number of bac- teria. In Bacillus subtilis all but 271 of bacterium’s ~4100 genes could be knocked out.

However, comparative genomics revealed that proteins’ length may be affected by additional factors. In 2002 it was shown that in bacterium Escherichia coli and the archaeon Archaeoglobus fulgidus, protein sequences with no homologs are, on average, shorter than those with homologs [1]. Most experts now agree that the length distributions are distinctly different between protein sequences with and without homologs in bacterial and archaeal genomes. In this study, we examine this postulate by a comprehensive analysis of all annotated prokaryotic genomes and focusing on certain exceptions.

Synthetic Biology As a Technoscience: the Case of Minimal Genomes and Essential Genes
Published in Studies in History and Philosophy of Science (epub ahead of print) Synthetic Biology as a Technoscience: The Case of Minimal Genomes and Essential Genes Massimiliano Simons, Ghent University [email protected] Department of Philosophy and Moral Sciences, Blandijnberg 2, BE-9000, Ghent Abstract This article examines how minimal genome research mobilizes philosophical concepts such as minimality and essentiality. Following a historical approach the article aims to uncover what function this terminology plays and which problems are raised by them. Specifically, four historical moments are examined, linked to the work of Harold Morowitz, Mitsuhiro Itaya, Eugene Koonin and Arcady Mushegian, and J. Craig Venter. What this survey shows is a historical shift away from historical questions about life or descriptive questions about specific organisms towards questions that explore biological possibilities: what are possible forms of minimal genomes, regardless of whether they exist(ed) in nature? Moreover, it highlights a fundamental ambiguity at work in minimal genome research between a universality claim and a standardization claim: does a minimal genome refer to the minimal gene set for any organism whatsoever? Or does it refer rather to a gene set that will provide stable, robust and predictable behaviour, suited for biotechnological applications? Two diagnoses are proposed for this ambiguity: a philosophical diagnosis of how minimal genome research either misunderstands the ontology of biological entities or philosophically misarticulates scientific practice. Secondly, a historical diagnosis that suggests that this ambiguity is part of a broader shift towards technoscience. Keywords: Minimal genome ; essential gene; Mycoplasma ; Craig Venter; synthetic biology ; technoscience Competing interests No competing interests to declare.

Eukaryotic Cell Eukaryotic Cells Are Defined As Cells Containing Organized Nucleus and Organelles Which Are Enveloped by Membrane-Bound Organelles
Eukaryotic Cell Eukaryotic cells are defined as cells containing organized nucleus and organelles which are enveloped by membrane-bound organelles. Examples of eukaryotic cells are plants, animals, protists, fungi. Their genetic material is organized in chromosomes. Golgi apparatus, Mitochondria, Ribosomes, Nucleus are parts of Eukaryotic Cells. Let’s learn about the parts of eukaryotic cells in detail. Parts ot Eukaryotic Cells Cytoplasmic Membrane: Description: It is also called plasma membrane or cell membrane. The plasma membrane is a semi-permeable membrane that separates the inside of a cell from the outside. Structure and Composition: In eukaryotic cells, the plasma membrane consists of proteins , carbohydrates and two layers of phospholipids (i.e. lipid with a phosphate group). These phospholipids are arranged as follows: • The polar, hydrophilic (water-loving) heads face the outside and inside of the cell. These heads interact with the aqueous environment outside and within a cell. • The non-polar, hydrophobic (water-repelling) tails are sandwiched between the heads and are protected from the aqueous environments. Scientists Singer and Nicolson(1972) described the structure of the phospholipid bilayer as the ‘Fluid Mosaic Model’. The reason is that the bi-layer looks like a mosaic and has a semi-fluid nature that allows lateral movement of proteins within the bilayer. Image: Fluid mosaic model. Orange circles – Hydrophilic heads; Lines below – Hydrophobic tails. Functions • The plasma membrane is selectively permeable i.e. it allows only selected substances to pass through. • It protects the cells from shock and injuries. • The fluid nature of the membrane allows the interaction of molecules within the membrane.
