- Do mutations makes super powers?
- Hey mom!!! do you know what is mutation ?
- Hey son! Good question you can ask your teacher tomarrow after class
- Mr. Dunn WHAT is a mutation? HOW does it mutate DNA? WHAT are the different ways it can affect DNA?
- Good questions.. Let's talk about DNA first
- DNA???
- Yes... All the instructions for the growth of living organisms are found in the long, helical molecule known as DNA.
- I am ( DNA) unique there can not be any copy of me!!!!
- So... DNA plays role in motation???
- Yes. The word mutate means to CHANGE and mutation is any random change in the DNA of an organism or a cell.
- Oh waw... How do chenges happen in DNA ???
- The changes can happen through external factors like X-rays and radioactvity. UV solar radiation is absorbed by our skin cells, which can cause mutations to appear as these cells grow.OR
- Or?
- How do mutations can make superpower???
- Internal factors: A cell divides and duplicates its DNA incorrectly.
- The human chromosome number is 46, with 23 from an egg and 23 from a sperm cell.
- Chromosomes???
- Chromosomes are made up of DNA and proteins, are highly organized, and have lots of genes on them.
- For example?
- Some of the examples of chromosomal mutation include duplication, deletion, inversion, tranlocation, and more...
- So... The genes they regulate may be impacted by mutations that change their genes. These interactions can result in mutations that are not related to the gene itself.
- Mutations that don't cause any significant changes are called "neutral" mutations.
- oh waw!!!!
- interesting....
- Mutations can be GOOD or BAD
- So what happens when a mutation is BAD?
- They lead to diseases, like cancer and cystic fibrosis.
- What about a GOOD mutation???
- It can allow an organism to more readily adapt to its environment.
- Mutations in some genes that confer superpowers.A nonsense mutation in the ACTN3 gene, which works in muscles, allows people who have it to be super-fast and athletic.
- It seems SO... impossible that I could transform into a superhero like Spider-Man after being bitten by a radioactive beast.
- Hahah!!!! you are correct
- so are mutations involved in the process of evolution?
- Evolutionary processes depend heavily on mutation. Mutation is the fundamental reason for all genetic variation. Mutation is important as the first stage of evolution because it generates a new DNA sequence for a specific gene and a new allele. .
- Amazing!!
- Now you have the answers to your questions.
- Yes... Thank you!
