BCA 210 Study Guide – Exam 2 Terms: Audion tube: Created by Lee de Forest‚ this improved the clarity of radio signal reception in 1907. This detected radio waves and pin points sounds. Lee de Forest perfected this glass bulb. Payola: 1960s‚ the practice of accepting payment to play specific recordings on the air. Disc jockeys were charged for bribery for accepting money to play music‚ the most famous‚ Alan Freed who worked in Cleveland who was credited with coining the term for rock ’n’ roll

DNA as a Key Witness Criminals‚ often unknowingly‚ leave parts of themselves behind. These pieces are not always visible to the untrained eye. Hair‚ skin‚ blood‚ and fingerprints all contain elements that are unique to each person. It is with DNA testing and fingerprinting‚ that criminals can be identified and crimes can be linked. This system of testing and matching has become the “most essential and reliable method of catching criminals” in the United States (Lynch 67). Advancing technology

EXAM-1 STUDY GUIDE DUE ON FEBRUARY 28TH PLEASE SUBMIT IN THE DROP BOX IN MICROSOFT WORD. CHAPTER-1 The Microbial World and You List several ways in which microbes affect our lives. Help maintain the balance of living organisms and chemicals in our environment. Marine and fresh water microorganisms form the bases of the food chain in oceans‚ lakes‚ and ricers. Soil microbes help break down wastes and incorporate nitrogen gas from the air into organic compounds‚ thereby recycling chemical

DNA and Crime Deoxyribonucleic Acid - the fingerprint of life also know as DNA was first mapped out in the early 1950’s by British biophysicist‚ Francis Harry Compton Crick and American biochemist James Dewey Watson. They determined the three-dimensional structure of DNA‚ the substance that passes on the genetic characteristics from one generation to the next. DNA is found in the chromosomes in the nucleus of a cell. "Every family line has it’s own unique pattern of restriction-enzyme DNA

DNA fingerprinting is a way of identifying a specific individual‚ rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology‚ it has been around since at least 1985‚ when it was announced by its inventor‚ Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal

For over a decade‚ there has been a controversial issue dealing with building a national DNA database. This issue has been brought up over the discussion of the actual database and what kinds of effects will come out of it‚ if it actually happens to go through. Some people think the database will be a force in crime fighting. Others think it is a violation of civil liberties. In the early 1900s‚ “fingerprinting‚” a new crime-fighting database‚ was developed. With the exception of identical

Recombinant DNA Report Our final annotated gel image sums up the successful experiments we performed over the course of 8 weeks. The image will be referred to throughout the report: Lane 1: 10 µL of ladder. Lane 2: 20 µL of a pAMP- EcoRI/HindIII double digestion. Within the double digestion‚ one can find 8 µL of pAMP‚ 1 µL of the EcoRI enzyme‚ 1 µL of the HindIII enzyme‚ 5 µL of 10x Buffer 2.1‚ and 35 µL of water. A total volume of 50 µL was present

chromosomes are very long compact coils of DNA (Deoxyribonucleic Acid) that store all the information that the body inbeds such as how one looks and functions. This paper will first describe the structure of DNA; second discuss how the structure of DNA allows it to serve as the basis for inheritance‚ third examine how meiosis allows DNA to be divided into gametes and finally‚ describe how this relates to Gregor Mendel’s patterns of inheritance. The structure of DNA DNA is a thread formed by two strands
