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:

Question In general‚ which is worse – acid or base conditions? Answers and Discussion Obviously a balance is required. The neutral pH is 7.0‚ however the natural pH of sea water is typically around 8.2 and that of fresh water is typically around 6.5. The answer to the question depends very much on whether or not we are discussing the environment or human health. Human Health: Our skin is slightly acidic (pH 5 to 5.5) and we can withstand low pH values quite readily. If we ingest or touch water which

Setting the stage for strategic compensation and bases for pay Paulette Harris Professor Christopher Zapalski Compensation Management - BUS 409 July 24‚ 2011 1. Describe the three main goals of compensation departments. Compensation professionals promote effective compensation systems by meeting three important goals: 1. Internal consistency 2. Market competitiveness 3. Recognition of individual contributions. Internal Consistency – Internal consistent compensation

DNA REPLICATION At the replication origin DNA helicase attaches to a strand of DNA and begins to break apart hydrogen bonds in order to unravel a section of the double helix. The section of DNA that is unwound is called the replication bubble and the “Y” shaped sections are called the replication forks. In order to stop the unwound section from binding back together‚ single strand binding proteins react with the single strand portions on the DNA causing them to stay separated. Although the leading

Baldwin Park Naval Base Redevelopment Project In 1993‚ an announcement was made that the Orlando Naval Training Center would be closed. The city of Orlando saw a good chance to develop the base property into a mixed-use neighborhood and help establish it to become apart the community once again. The city’s property was well-planned and organized by the Base Reuse Commission that involved citizens who met numerous times over the course of two years. During the meetings it was agreed upon

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled

Hailie Armstrong Ms. Gorges U4 L8 Chemistry 11/19/14 Modeling Molecules Introduction: You can represent a molecule two-dimensionally‚ as a structural formula or electron dot structure. Although such models are useful in certain contexts‚ they do not accurately represent bond angles between atoms or shapes of molecules. In this activity‚ you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the

DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

Setting the Stage for Strategic Compensation and Bases for Pay HR Practices January 30‚ 2011 Describe the three main goals of compensation departments The three main goals of the compensation departments are internal consistency‚ market competitiveness and recognizing individual contributions. When companies set the pay for jobs they want to be consistent with pay grade in regards to the job description. Higher pay is given to jobs that have greater responsibilities and greater qualifications
