DNA Day Essay

(due 2/9/15)

2015 Question

In 1969, Jonathan Beckwith, James Shapiro, and Lawrence Eron isolated the first gene, the Lac Z gene from E.coli. At that time, genes were thought to be discrete, contiguous segments of DNA that coded for functional protein products.

Using our current understanding of the human genome, choose a phenomenon related to gene structure, products, or regulation that expands this definition of a gene. Explain the phenomenon and provide three specific examples of it in the human genome.

Essay Contest Rules

1.

Essays will be accepted from high school students (grades 9-12) in the US and internationally. A

teacher or administrator must submit the essay and authenticate that the submission is the original work of the student. Parents may submit the essays of home-schooled students only. Only one entry may be submitted for each student.

2.

All essays must be written in English and are limited to 750 words, including in-text citations. Essay titles are optional and will be counted towards the word limit. Reference lists do not count toward the 750 word limit.

3.

Each teacher may only submit six student essays per class, for up to three classes.

4.

Essays must be submitted electronically through the ASHG submission site no later than 5:00 pm EST

on March 6, 2015. The ASHG submission site will open on January 14, 2015. Essays mailed, faxed, or emailed to the Society will NOT be accepted. Once submitted, essays cannot be changed or revised.

5.

The text of student essays must be original prose unless quotations are explicitly noted. Plagiarism

will not be tolerated. Essays found to contain the uncited work of others will be disqualified, and the student’s teacher will be notified. This video from Carteret Community College Library gives a great overview of what constitutes plagiarism.

6.

Essays must include at least one reference. References must be clearly documented with both intext citations and in the references list (the reference list should be separately entered into the

“References” section of the submission page). Students may use either APA or MLA style for citing references. There is no restriction on how many references students may use. Quality of references will be considered by judges when scoring. General references such as Wikipedia are considered low-quality, whereas primary literature from research journals

(see http://www.ncbi.nlm.nih.gov/pubmed/) is considered high-quality.

7.

Only classroom teachers are eligible for the equipment grant. Teachers of first-place winners from

2012, 2013, and 2014 are not eligible for equipment grants in 2015.

Please note that text from essays may be used for research purposes to identify misconceptions, misunderstandings, and areas of student interest in genetics. Student text may be published on the ASHG

Web site, newsletter or in other ASHG-supported publications.

Common Pitfalls

Summarized below are some of the most common issues judges flag in reading submitted essays. Note that judges, rather than student essays, are quoted below to obscure the identity of the essay in reference.

1.

A focus on details to the detriment of demonstrating a clear understanding of the big picture. Judges are much more forgiving of errors in details than errors in fundamental concepts and larger ideas.

Example: "Got the small facts right and the big ones wrong."

2.

Sweeping and grandiose overstatements of the current/future state and/or utility of biotechnology or biomedical science.

Example: "It's concerning that this student believes gene therapy is a 'prevalent medical cure for deadly diseases.' "

3.

Inaccuracy in technical language.

Example: "The student confuses genes and alleles."

4.

Description of phenomena or advances with no explicit argument connecting them to the question.

Example: "Student does not link the discovery of the DNA double-helix structure to the development of microarrays, DNA fingerprinting, and probe technology. The student simply describes all four of these things."

5.

Misunderstanding the nature of a scientific advancement.

Example: "Cites Watson and Crick as discovering DNA rather than the structure of DNA."

6.

Lack of in-text citations in general, or lack of citations for information that is not considered common knowledge. In the latter case, students often make wild, unsupported claims that may be tempered if they must find references to support their information.

Example: "Many good references are listed but the information in the essay has no citations - not even information that is highly technical. Lack of citations is inappropriate, leaving the reader to surmise or guess at the source."

7.

Using out-of-date references. Scientific understandings change very rapidly, and references that are more than five years old are likely to espouse outdated ideas.

Example: "One concern I have with this essay (reason for rating references low) is that a reference from 2001 is used. Genomic medicine changes so rapidly that many publications from 2-3 years ago are outdated, never mind 12 years ago!"

8.

Using too many quotes. Although occasional use is warranted, too many quotes lead judges to think the author has no thoughts of their own.

Example: "Although this essay is well-written, most of the essay contains sentences directly quoted from the references rather than the student describing the facts in his/her own words. I could not determine if the student understood the content."
