Chapter 12 Blog: Gene Expression at the Molecular Level (Aarti)

Page history last edited by Aarti Patel 13 years, 4 months 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 article is about the regulation of telomerase activity.   It talks about the link between the protein TRF1 and telomerase.  It explains that the two are not directly associated.  The inhibitor PINX1 links the two.  This maintain homeostasis in telomerace activity.


This video explain the role of telomerase.  It explain the fact that chromosomes shorten during ever replication, therefore it needs uncoded areas at the end.  It also explains how telomerase adds a telomere at the end of the DNA strand.
This video explain the process of transcription.  It explains the role of the tRNA and ribosome.  It shows the two subunits of ribosomes and how they attach.  It also shows how the polypeptide chain is formed.
