What's the Deal with Random Mutations? 🎲

  • Mutations are described as random changes. Imagine trying to predict the roll of a dice – it’s just as tough predicting a mutation.
  • Even if we’re unsure about what "truly random" means, mutations are surely unpredictable.

Can Organisms Control Mutations? 🧬

  • Nope! Organisms can't direct mutations to achieve a specific outcome. It's not like ordering your favorite pizza.
  • There’s no "intentional" mutation mechanism discovered in organisms. Think of it like trying to find a unicorn.
  • However, some organisms might control their overall mutation rate a bit. This is like controlling the volume on a radio, but not the song that plays.

Where Can Mutations Happen? 🔍

  • Anywhere in the DNA! But, some DNA bases are more likely to mutate because they change chemically more easily.
    • Real-world example: Just like some ice creams melt faster under the sun due to their ingredients!
  • A DNA's position also affects mutation chances. How? Because coding DNA (that makes proteins) and non-coding DNA (like DNA punctuation) have different "jobs", and that affects mutation rates.
