Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins. Prokaryotes

Chapter 3 Cell Structure and Function Section 3.1: Cell Theory: Cells are the smallest building unit of living organisms that can carry out all processes required for life. Almost all cells are too small to see without the aid of a Microscope. Although glass lenses used to magnify images for hundreds of years‚ they were not enough to reveal individual cells. The invention of Compound microscope was in the late 1500s by the Dutch eyeglass maker Zacharias Janssen. In 1665‚ the English scientist

non-membrane bound structure. Composed of proteins and nucleic acids found within the nucleus. Ribosomal RNA (rRNA) is transcribed and assembled within the nucleolus. Three major components of the nucleolus are recognized: the fibrillar centers (FC)‚ the dense fibrillar components (DFC)‚ and granular components (GC). The DFC consists of newly transcribed rRNA bound to ribosomal proteins‚ while the GC‚ contains rRNA bound to ribosomal proteins that are beginning to assemble into ribosomes. However‚ it

Give an account of protein structure and function Protein structure 1 Proteins consist of amino acids joined together (in chains) 2 A protein is unique because of the sequence of amino acids 3 The amino acids are joined by strong peptide bonds 4 to produce the primary structure 5 Further (weak) hydrogen bonding between acids 6 produce the secondary and tertiary structures A maximum of 4 marks can be gained from this section. Protein function 7 Some proteins are enzymes + named example

Thus the basic functions of an OS are – 1. Process Management – Managing the programs that are running. 2. Memory Management – Managing and rationing the memory between processes and data. 3. Storage Management – Managing the permanent Storage of data on disks or other media 4. I/O Management – Managing the input and output 5. Device / Resource Management – Managing devices and resources and allowing the users to share the resources 6. Security and Protection – Securing the

1.2 Basics of Functions and Their Graphs Introduction to Relations Domain and Range of a Relation Any set of ordered pairs (x‚y) is called a relation in x and y. Furthermore‚ The set of first components in the ordered pairs is called the domain of the relation. The set of second components in the ordered pairs is called the range of the relation. Definition of Function and Vertical Line Test Definition of a Function Given a relation in x and y‚ we say “y is a function of x” if for every

Week 1 Assignment 2 DQ1: This week we were introduced to the basic functions of our computers. The three things I learned are: 1. I’ve always known that our computers come preloaded with the operating system‚ although I didn’t know that the Microsoft applications I have on my computer are compatible on a MAC. For example‚ MS word‚ MS PowerPoint‚ and MS Excel. 2. One of the things I found important to share with others was the use of external storage devices. I learned the hard way my senior

Cell Bio Bites Topic: Ribosomal Function and Ricin Relevance of Ricin and Ribosomes Relevance of Ricin and Ribosomes Most foods from the four food groups contain protein. Protein is manufactured by the ribosome. In contrast to ribosomes‚ ricin breaks up proteins and blocks protein synthesis. In that perspective‚ ribosomes can be seen helpful and ricin as useless and lethal to a somatic cell. Luckily‚ since ricin can stop protein synthesis‚ ricin is being experimented to block diseases’ protein

leaders are students of human personalities‚ motivation and communication. They can influence their personnel to view situations from their perspectives. Leading also involves supervision of employees and their work. Controlling Controlling is a function of management that involves measuring achievement against established objectives and goals. It also requires managers to be able to identify sources of deviation from successful accomplishment and to provide a corrective course of action. Managers
