membrane regulates the movement of water‚ nutrients and wastes into and out of the cell. Inside of the cell membrane are the working parts of the cell. At the center of the cell is the cell nucleus. The cell nucleus contains the cell’s DNA‚ the genetic code that coordinates protein synthesis. In addition to the nucleus‚ there are many organelles inside of the cell - small structures that help carry out the day-to-day operations of the cell. One important cellular organelle is the ribosome. Ribosomes

Biology 2A 2/23/14 Genetic engineering is making changes in the DNA code of a living organism‚ working almost the same. It has many purposes including clones‚ perfect humans and cures for genetic diseases. Gel electrophoresis is a powerful tool used for separation and analysis of macromolecules and their fragments‚ based on their size and charge. You place the DNA in the gel. DNA is a long‚ strand-like molecule where genes are written in genetic code. Extracted enzymes recognize and extract the

Structural Isomers • molecules with the same molecular formula but with different arrangements of atoms • differences in the shape of isomers lead to differences in their physical & chemical properties • For example‚ galactose‚ glucose and fructose have the same molecular formula (C₆H₁₂O₆) but different structures (figure 6 page 30) • glucose itself has 3 different structural isomers in dry state‚ glucose has a linear structure‚ but when dissolved in water‚ the molecules fold on itself

Lovett Lab Report # 4 Experiment 7&8 1 Bacterial Growth and One Step Burst - T7 Phage I. INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria means it multiplying

In this essay I am asked to review and assess the case study of the Woody 2000 project. The concept of the project was simple enough‚ expand the workspace in order to increase productivity and remain competitive within the surrounding area without having to move to a different location. The initial project‚ I feel was not well conceived at all. I feel that the time spent actually planning out who’s‚ where’s and why’s would have benefited the company’s efforts and efficiency dramatically. What

ABSTRACT The microevolution of Alu element TPA-25 was tested in the experiment through the examination‚ observation‚ and analysis of population alleles distribution under the Hardy-Weinberg Theory of Genetic Equilibrium. Alu elements affect the genome by causing insertion mutations‚ recombination between elements‚ gene conversion‚ and alterations in gene expression. In the lab PCR was used to amplify a short piece of DNA from human genome which allowed us to look for a DNA sequence called an Alu

Biology textbook- pg. 80 3) Distinguish between the autotrophic and heterotrophic nature of plants and animals. Animals have heterotrophic cells; hence‚ they live off nutrients of other species by eating. Most plants have autotrophic cells‚ which allow them to generate their own food with photosynthesis. 4) Explain the following statement: ‘All living things depend on plants’. As animals are heterotrophs‚ they need to eat other species to survive. If mammals only depended on other mammals‚ there

Biology Article Isaac Ayers Professor Carol Hoban SCI115012VA016-1136-001 Introduction to Biology August 2‚ 2013 * The title of the article that I have chosen for this assignment is “The Era of Memory Engineering Has Arrived”. The article begins by explaining a basic plot of a sci-fi movie in which the main character has had his memories altered by scientists using electrode caps. The article then goes into detail about how a new set of experiments‚ led by MIT neuroscientists

Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both are at same temperature. The Kinetic Theory can be used to describe the three physical states of matter namely‚ solid‚ liquid and gas. In this theory‚ some basic assumptions has to be made: a) all matter
