DNA Structure and Replication - Online Resources

As you reenter school life after the long weekend, it's worth checking in to make sure that you understand both the concepts before you finalize the details on your DNA project. We'll go over all this stuff in class, of course, but it's a good idea to use all the resources available to you, including these two terrific sources: bozemanbiology and crashcourse. Taking 23 minutes to watch these two videos can help to illustrate the concepts that are in the book and in your notes. Put those together with my earlier post on Transcription and Translation and you should be in great shape. See you on Tuesday.

DNA --> mRNA --> Protein

DNA --> mRNA --> Protein As you review the processes of transcription and translation, remember that there are many videos online that can help to illustrate what's going on in your cells. Some of these are extremely detailed and accurate from a molecular modeling standpoint. Others are more schematic (simple shapes used to represent the actual shapes of the molecules), and these can be easier to understand. This one is somewhere in the middle, and I like the narration and pace.

 Other teachers are posting podcasts online, which I think are great because they include more personable explanations. This is more like watching/listening in class. We watched Paul Andersen's podcast on cells in the fall. Here's his on Transcription and Translation, which is nice and clear. He also uses the same cookbook metaphor that we talked about in class.

Resources for Unit on Animal Development

As we work through this unit on animal development, here are some resources that you might find useful.

Khan Academy video on Embryonic Stem Cells.

Many animations on YouTube show the stages from fertilization through gastrulation. I found this one particularly clear:


Watch a few, and let the class know which ones you find helpful (videos or other websites). Post links below in Comments.

Helpful Meiosis Videos

The teacher in this video does a good job comparing the processes of Mitosis and Meiosis (# of divisions, end products, goals).



This video makes the details of meiosis (especially to process of crossing over) very easy to understand. I have to get some of those magnetic beads so we can do this in class.

Henrietta Lacks - A Donor's Immortal Legacy - NPR Story

In response to a question about whether cancer cells live forever, we talked in one class about Henrietta Lacks. Here is the link to the NPR story and book, The Immortal Life of Henrietta Lacks, by Rebecca Skloot.

Unregulated Cell Division

Throughout this unit, we'll be comparing healthy cell growth with unregulated cell growth. This video animation is a good one.
