In Chapter 6-7 & 9 (we come back to 8 in the next module) of the Concepts of Biology text, the emphasis turns to DNA and the process of cell division and genetics. Respond to the following two prompts relating to these three chapters:
- In section 7.3 we learn about errors that can occur in the process of meiosis, and several types of errors are mentioned. Select of these types of errors (e.g. chromosome number, non-disjunctions, etc.) and provide a brief description of the error (in your own words). Then do a little bit of online research related to the type of error and identify and describe one disease or condition that can result from this type of error (example – Trisomy 21 is where there is an extra chromosome in the 21st pair, and is responsible for the condition of Down Syndrome). Be sure to describe the symptoms and any treatments that are associated with the condition you select.
- The concept of DNA replication is a complicated one – and often pretty difficult for us to visualize/grasp. Review 9.2 regarding DNA replication and then do some online searching to find a reference or resources (not one of the ones on Padlet) that does a good job of explaining this process. In your post, identify:
- One aspect of process of the DNA replication that the video/animation does a good job of describing, or that made things easier to understand (for instance, if you didn’t understand what Okazaki fragments were and the video helped explain it, describe what makes the concept more understandable in the video/animation)
- At least one aspect of the process that you are still not quite grasping (that’s ok if more than one, it’s complicated!)
