Normal gene: ATGGCCGGCCCGAAAGAGACC Mutated gene: ATGGCCGGCACCGAAAGAGACC Normal protein: Met-Ala-Gly-Pro-Lys-Glu-Thr Mutated protein: Met-Ala-Gly-Thr-Glu-Arg-Asp - base addition-missense The timing of a mutation during development has negligible effects on the severity of the genetic defect. - FALSE A gene created from the fusion of two gene fragments is considered a - chimeric gene. If a cell contains 20 units of DNA during G2, it will have 40 units of DNA in S. - FALSE In a tetraploid species, a euploid individual would have ___sets of chromosomes. - 4 For any given species, cells in metaphase II of meiosis would contain 2× more genetic material than cells in metaphase of mitosis. - FALSE Which of the following are incorrectly matched for a single-factor cross? - F2 generation / result of P cross A cross of a true-breeding smooth pod and yellow pod plants results in all smooth pod offspring. This indicates that - two of the answers are correct. Yellow and smooth are variants of the same gene, and smooth is the dominant trait.

  ...Aaron Nussdorf English 4/24/14 Final Paper In both “The Hunger Games” and “Zone One” both authors tell the story of what the world is like today in an exaggerated fashion. Although we don’t know exactly the time in which both books are set , we do know that they are approximately around today’s present or in the near future. In each book the authors use their story telling to point out the flaws in today’s government and society. The first thing I noticed in “The Hunger Games” is that there were 13 districts and one capital. I immediately related this to our past as a country with the 13 colonies and England being the capital. Every district had its own specialty and seemed to be divided by some type of class. One might be agriculture , another might be coal mining , another might be fixing damaged objects. Never in the book do you really see people from other districts getting along. In the sequel to the book you will see all the colonies gathering together to fight the overwhelming power of the capital , this can definitely be related to the American Revolution. However , these things are all in the past and do not help me prove my thesis. What did grab my attention were the electrical gates and the use of public humiliation to suppress any type of rebellion in the colonies again. I forgot to mention that the reason for the Hunger Games was because of a previous rebellion , and I guess that is when they split them into 13...

  ...Ch. 20 Vocabulary List 1. Genetic engineering – The direct manipulation of genes for practical purposes. 2. Gene cloning - The production of multiple copies of a gene. 3. Restriction enzyme – A degrading enzyme that recognizes and cuts up DNA (including that of certain phages) that is foreign to a bacterium. 4. Restriction site – A specific sequence on a DNA strand that is recognized as a cut site by a restriction enzyme. 5. Recombinant DNA – A DNA molecule made in vitro with segments from different sources. 6. Sticky ends – A single-stranded end of a double-stranded DNA restriction fragment. 7. Cloning vector – An agent used to transfer DNA in genetic engineering. A plasmid that moves recombinant DNA from a test tube back into a cell is an example of a cloning vector, as is a virus that transfers recombinant DNA by infection. 8. Nucleic acid hybridization – Base pairing between a gene and a complementary sequence on another nucleic acid molecule. 9. Nucleic acid probe – In DNA technology, a labeled single-stranded nucleic acid molecule used to tag a specific nucleotide sequence in a nucleic acid sample. Molecules of the probe hydrogen -bond to the complementary sequence wherever it occurs; radioactive or other labeling of the probe allows its location to be detected. 10. Complementary DNA (cDNA) – A DNA molecule made in vitro using mRNA as a template and the enzyme reverse transcriptase. A cDNA molecule therefore corresponds to a gene, but...
