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:

Whitney Barnes: SENSATION & PERCEPTION WORKSHEET a) Briefly describe the path of information from the targeted sensory organ (i.e. eye‚ ear‚ skin‚ etc.) to the brain. Include a synthesis of terms/information from both Chapter 2 - Biological Basis of Behavior and Chapter 3 - Sensation and Perception in your description. When you are using your ears you can choose what you want to listen to‚ but you cannot choose what you are hearing. The first step is when the pinna collects sounds that enter through

Literature Review and Project Proposal AS6P01 Title: DNA Profiling Techniques in Forensic Science Abstract Since 1985‚ DNA profiling in forensic science has become very important in this virtual era of technology and in the world of science that solves both major and minor crimes. Small traces of DNA are considered in all circumstances from how the DNA was collected to fully obtaining the profile in its significant form. Traces of sweat‚ blood and semen are the most common type’s evidence

Does DNA profiling in its current state offer foolproof identification? What needs to be in place for it to be error-free? Should all incarcerated criminals be forced to give samples? Should convicted juveniles? Should the general public be required to give a DNA sample? The pros of DNA profiling are that it can be used to quickly eliminate a suspect‚ saving time in searches for perpetrators. And it can provide compelling evidence to support a conviction and‚ most importantly‚ reduce the chances

Theories as the Basis for Nursing Practice Seema R Sulemani Homeland University NURS 211 SF12 October 14‚ 2012 Abstract Theory development is the fundamental step for expansion of nursing knowledge. The knowledge has been borrowed from different disciplines to build the nursing theories. The categorization of theories is based on their scope of practice. The grand nursing theories are the most complex and abstract in their nature. Middle range theories are inducted mostly from grand nursing

There are massive problems with manipulating the DNA. DNA manipulating can cause of the ethical issues or belief that god should have ultimate power over nature; safety issues DNA manipulation can bring long term negative effects‚ detrimental effect on genetic diversity‚ high price‚ and will disrupt the natural ecology. There might be some advantages with the manipulation DNA such as eliminating illness and disease in unborn children‚ but it has really small possibility to happen. Even if it success

DNA SPOOLING ISOLATION OF DNA FROM ONION INTRODUCTION This project will demonstrate several basic steps required for isolation of chromosomal DNA from cells. To extract the chromosomal DNA‚ both the cell membrane and the nuclear membrane must be broken open. This is accomplished by disrupting the membranes with a solution of detergent and salt‚creating a cell homogenate. Once the DNA is released from the nucleus‚ it must be protected from nucleases‚ enzymes which will degrade the DNA. Keeping

DNA TECHNOLOGY How is DNA technology used in law enforcement? There are many different ways it is used‚ but it is mostly used to solve crimes. Much like deaths‚ rapes‚ or even big robberies. DNA is a way to identify a person by: blood‚ hair‚ skin‚ saliva etc... That is why when people are trying to discover a murderer they are very careful when they are collecting evidence.That is why when something occurs‚ everything is blocked off‚ and only investigators could pass into the area
