BIO 225 – Exam 2 Review Sheet Chapter 9 1. Know the anatomy of the structures that make up the prokaryotic cell. Know their functions. Know any clinical significance each structure might have and if it is a target for antibiotics. (On separate sheet) 2. Know the differences between Gram positive and Gram negative cell walls. * Gram positive cell wall * In addition to many layers of peptidoglycan‚ the cell wall of Gram-positive bacterials cells also contain: * Teichoic

Basic chemistry of a cell Properties of water – – – Life on Earth began in water and evolved there for 3 billion years before spreading onto land. Modern life‚ even terrestrial life‚ remains tied to water. All living organisms require water more than any other substance. Human beings for example‚ can survive for quite for a few weeks without food‚ but only a week or so without water. – – – Water is deceptively simple. It is shaped something like a wide V‚ with its two hydrogen atoms joined

on which structures? DNA‚ the body’s genetic makeup‚ including Joseph’s predisposition to disease‚ is found primarily in the nucleus‚ but also in the mitochondria. To repair itself‚ the messenger RNA‚ having received a transcribed copy of DNA from the nucleus‚ binds to a ribosome and pairs with transfer RNA for protein synthesis and

Comparing Cell Theory Parts to real world applications Cell Membrane compared to a house- Cellmembrane = screen on porch or window‚ lysosome is garbage disposal or recycling bin‚ vacuole is a water storage tank‚ er are hallways‚ mitochondria is a furnace or electrical generator‚ ribosomes could be the kitchen oven that’s making dinner‚ the nucleus is the parent Lysome- Cell Wall- probably be like a city wall surrounding the city‚ protecting it and defining the boundaries (osmotic control‚ protection

The Different Roles of Macromolecules in Biology.There are four types of macromolecules that I am going to describe: Proteins‚ carbohydrates‚ lipids and nucleic acid. I will also describe the functions and why they are important in our bodies. Proteins Proteins are polymers of amino acids that are joined head-to-tail in a long chain that is then folded into a three-dimensional structure unique to each type of protein. The covalent linkage between two adjacent amino acids in a protein (or polypeptide)

YOUR NOTES UNIT 2 NOTES DNA (deoxyribonucleic acid) DNA Functions • Stores genetic information and copies itself (replication) to pass on the information • Contains genes (instructions to make proteins) • Instructs cell’s activities DNA Structure • DNA is a polymer of nucleotides • Chromosomes (DNA strand + associated proteins ie. Histones wrap DNA around like a spool = condensed chromatin) ↓ genes (sections of a chromosome that codes for a protein) ↓ nucleotides (3 parts:
