Week 9: DNA Mutation
What did you learn this week?
I learned more about how a mutation in DNA can impact both the genotype and the phenotype of a person. There are many different types of mutation, but we focused on the aspects of point mutation, namely deletion, insertion, and substitution. Most mutations are neutral and do not alter the function of DNA, but some mutations can be beneficial or harmful.Are you able to relate what you learned to what you already know?
We already learned about how organisms function within an ecosystem, and so theoretically if one member of a food chain has a genetic mutation that creates better chances of
survival from their predators, then that could alter the function of an entire ecosystem. New learning is always impacting our prior knowledge, building upon what we already know to make more sense of the world.
What are new or remaining questions?
Now that we know about a few different mutations and how they impact phenotypes in organisms, what other kinds of mutations can affect the genetic makeup of an organism, altering its phenotype?


I like how you mentioned that most mutations are neutral, but they can also have benefits and harms to organisms.
ReplyDeleteElsa, I really like how you were able to connect this week's learning back to previous weeks' learning about food chains. Mutations are also the driving cause of evolution for organisms which is cool! Great work!
ReplyDeleteHi Elsa. I liked your question that you had. It got me thinking about phenotypes and how I want to explore them more. Great job!
ReplyDeleteHi Elsa! I also liked your questions and it is very interesting to think about that.
ReplyDeleteHi Elsa! I really like your connection to cause and effect within your blog post. I never thought about how a mutation in one organism could cause changes in the whole ecosystem. Great post!
ReplyDeleteHi Elsa, I enjoyed reading your question about how different mutations can affect phenotypes. It really had me thinking if this would positively affect or natively affect this process as a whole. Great question!
