Chapter 11: Nucelic Acid Structure, DNA Replicaiton, and Chromosome Structure (Lauren)

Page history last edited by Lauren Banjo! 13 years ago

In the first section of this page, you will write a daily summary of that day's class.  For example in  your chapter 2 blog, your first entry should be titled 9/3/10.  You should then write a one or two paragraph summary of that day's lecture, outlining the major points.  In the second section, you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.

This is an animation of helicase I made ALL BY MYSELF!!!



Is it the best animation ever? No. Is it very descriptive? No. but keep in mind this is over 60 frames and I drew the whole thing by hand. It took forever just for this 8 second animation!


So, it's helicase. Helicase is an enzyme (like pretty much everything ending in "ase"). Its job? It unwinds the DNA, just like I showed you in the animation. DNA needs to be unwound in order to start the replication process.

This article talks about the importance of telomeres. They are a sequence of nucleotides found at the ends of one's DNA. Their function is to serve as sacrificial nucleotides. They are unimportant in function so it's okay if they get cut off at the end of the DNA replication process. This stops important sequences from being cut off. Telomerase is a protein that makes more telomeres. It was given to mice in an experiment, and it showed anti-aging effects. Telomere dysfunction can lead to tissue degeneration.

This is the Human Genome Project. A genome is all of the organism's DNA. Our genome is made up of about 3 million base (A C G T) pairs and 25,000-30,000 genes. The goal of this project was to identify all the human genes. They were to be recorded and stored so they could be used for further studies. They were able to get DNA from donors by taking blood from females and sperm from males. It will help scientists communicate with each other by looking up a specific gene and posting what they know about it so others can read.

This is what this space is about. Great job. I appreciate the effort.
