biology DNA LAb

PCR/DNA lab is worth 1000pts,.

 Question: Do I have the Alu insert PV92 on my 16th chromosome; determined through polymerase chain reaction and gel electrophoresis?

Hypothesis:. HINT, ‘kinda’ spelled out in the test!

Test: We will isolate DNA from human cheek cells. We will then amplify a segment of chromosome 16 using PCR. DNA samples will be separated by different sized fragments using gel electrophoresis. Finally, using proper staining methods to make the DNA visible using Ethidium Bromide; we will be able to determine the genotype for the human Alu insert PV92.It will be +,+ (yes, Alu); -,- (no alu), or + ,-(one alu).

You will NOT need to include full materials lists, procedures or diagrams for this lab.

Each of these section headings should be included and followed by “See Gene Connection hand outs.”

Data is a Labeled diagram of your DNA photo results after gel electrophoresis and your observation journal.  *Observation Journal is Key here!

Analysis will include a discussion of Possible types of error and how they could have affected your results.

Conclusion as per rubric in paragraph format.

Biology/Earth science extra credit current events

Science Current Events
Earth Science/Biology
Fall 2013

You will choose an article or science related video of over 3+ pages or 45+ minutes on a science current event topic. It will fall into one (or more) of these categories:


·         Scientific discovery – for example, scientists find comets may have delivered the water found in earth’s oceans.

·         Science-related event – for example, the Japan earthquake/tsunami/nuclear plant meltdown; the launch of a space probe.

·         A cultural change/happening that involves science/technology – for example, bicyclists’ clothing that can act as a radar gun to show drivers how fast they’re moving.

·         Science in public policy – for example, a bill or law that deals with science ( i.e. cap on carbon emissions).


The article must be timely, meaning it’s been published within the past one/two months. Finally, technology articles are okay, but I will not accept any product announcements or reviews.


Create a write-up of your current event, summarizing the story and answering key questions. You will include a copy of the story you are citing or the golden page format for the video, movie or program.  

Science current events will:

Cite the news source, using the Oceana Golden page format for citations found on the Oceana website. Magazine Article:

Perlman, Jeff. “Sultan of Swat.” Sports Illustrated. 12 February 2001: 54-59.

Newspaper Article:

*  Taylor, Michael. “Potholes Scar Roads Across Region.” San Francisco Chronicle. 23 October 2005:

*  Give the title of the article, author’s name, and article date within the body of the summary.

*  Summarize the event in your own words, using complete sentences. Spelling and grammar count.

*  Your summary will answer the following questions:

·         Why did you choose this article?

·         What did you learn from the article, and what are your thoughts about this event/issue?


·         How does this event affect the world or region where it occurred?

·         How does this discovery advance science?

·         What does the discovery/event mean for our society?

·         What does this discovery/event mean for future work/the environment/humanity/etc.?

·         If the story is about a law or policy, how does the policy or law affect science/society?

Earth Science Reading

Read Ch 31.2 on galaxies, pgs. 839 - 846.  Take Cornell Notes.

Tech C-3: seperation of charged Dyes

“ Tech C ” Analysis Questions

6) Based on your results, what is the charge of each of the dyes you ran?  Why?  


7) The distance a dye runs is based on size of the dye, bigger molecules travel slower.  What are the relative sizes of your 6 dyes?


8) What conclusions can you make about your dyes?


9) In this activity DNA is NOT mixed with this loading dye but it will be when you load and test your DNA.  Where would you expect to find the DNA?

Drots Questions

1)  Draw  a pedigree of your drot and neighbors drot linage.  SHow you, neighbor two drotlinggs, dotling partner and 2 grand drots.  use diamond shapes and subdivide into six regions to shade for the pressence of each of your genes.  you pick whether you are shading dominant or reccessive.

2) What are all the possible genotypes for Drot tenticles?

3)   What are all the possible phenotypes for Drot tenticles?

 4) If you consider tenticles and body type , what are all the possble combinations for phenotypes and genotypes forthis pair of gene traits?

5)  Considering the three drot genes on the first chromosome, How many possible phenotype and genotypes are there?
