Mutation:Deletion
• What is a mutation?
A mutation is any change in DNA sequencing, mutations occur because of mistake copying the DNA or by exposure to certain environmental factor.
• What is deletion?
Deletion is a type of mutation where in the DNA sequencing, one or more of the nitrogen bases is unintentionally removed.
Deletion is a frameshift mutation meaning that everything after the mutation will be affected.
Deletion can lead to genetic diseases; cleft palate, heart defects, autoimmune disorders etc.
Reflection
I enjoyed writing this post because it helped me review on my types of mutations especially deletion, which I had a issue with covering because I wasn't here when she taught us. I've refreshed that deletion is a frameshift mutation along with addition and that substitution is a point mutation. Mutations are a very important factor in our lives because they effect the way we look and function.

I really like the way you made and set up your blog. It is really good that you picked something that you really needed to review so you could challenge yourself a little bit. You could have added the fact that deletion is only one out of three types of mutation.
ReplyDeleteThis blog tells what we need to know about deletion. I think that it is a bit small, but it still has everything. I wish you could have given some examples of mutagens.
ReplyDeleteYour blog was really good as it was able to get straight to the point while explaining it pretty well. I never knew what a frameshift mutation was and I did not initially understand it either. You probably could've included another visual like a picture or video.
ReplyDeleteI like how your post is very study-friendly and an effective study-tool. Did reviewing this topic help you? I think you could have included a video since your topic review was so brief.
ReplyDeleteI like how well you explained everything, it was very easy to understand. I'm glad that this topic was a good review for you since you were absent. Something that I would add is what the other forms of mutations are (addition/insertion and substitution).
