Polycomb Group-Mediated Repression of Homeotic Gene Expression in Drosophila
[ send me this paper ]
A 5 page paper discussing two possible actions of polycomb group (PcG) genes in repressing homeotic gene expression in Drosophila. One is that PcG binds to DNA through PcG response elements; the other is the dMi-2 and Hb combine to recruit PcG to DNA, though it may also be possible that Hb recruits dMi-2 directly to DNA. Bibliography lists 7 sources.

Prokaryotic Cells: Similarities and Differences Between Prokaryotic and Eukaryotic Cells and the Potential for Genetic Manipulation
[ send me this paper ]
A 9 page discussion of the cellular structure of these two broad categories of cells. Notes that prokaryotic cells lack a limiting nuclear membrane and are represented among single cell organisms such as bacteria and the blue green algae while eukaryotic cells are found in multicellular organisms. Describes the major structural components of these cells and emphasizes that even the most simplistic of these cells can have tremendous importance even to the most advanced of multicellular organisms. Notes that this importance can be particularly concerning in the case of genetic modification of disease causing single-cell organisms for the purposes of biological warfare. Bibliography lists sources.

Pseudoscience: Common Depictions Verses Scientific Fact in Homosexuality
[ send me this paper ]
A 5 page discussion of the inaccuracies regarding the root causes of sexual preference. Suggests that these inaccuracies are particularly damaging when they are misrepresented as scientific fact. Present real facts regarding homosexuality which would support the contention that sexual preference is genetically determined. Bibliography lists 4 sources.

Research Approaches To Extend Life Span In Lower Organisms
[ send me this paper ]
10 pages in length. The quest for life extension continues to preoccupy mankind's scientific endeavors. Research in the area of increased longevity in lower organisms has produced findings associated with environmental (external) implications (Jazwinski, 1996), the discovery of longevity genes (Varmus, 1997), caloric limitations to produce beneficial metabolic changes (Yamaza et al, 2002) and achieving the same benefits of calorie limitations without the associated depravation by way of molecular mimicry (Anonymous, 2002). Bibliography lists 11 sources.

Review of “Does Race Exist?”
[ send me this paper ]
A 5 page review of an article appearing in Scientific American in 2003 discussing genetic similarities and differences between and within those groups of humans that we commonly refer to as races. The authors discuss the role that Alu polymorphism carries in distinguishing broad groups of people and the limitations of using the measure to categorize humans. The authors explain that some who appear to be quite similar can be quite different genetically, while the reverse is also true. Bibliography lists 1 source.

Rhetorical Analysis: Stephen Gould
[ send me this paper ]
(5 pp) In this paper we will be examining a short piece of text (Chauvet Cave: The Discovery of the World's Oldest Paintings - 1996) by Stephen Gould which involves both science and technology, yet we will examine this work from a rhetorical perspective, first as a singularity, then in light of a broader context. Bibliography lists 3 sources. The student should note that the text used is included after the bibliography.
