Hey future biologist! Ever wondered why superheroes like the Hulk or Spiderman exist in comics? It&#39;s all about mutations! Let&#39;s dive in and unravel the secrets behind gene mutations. 🕸️💥

<ul>
	<li>A gene mutation is a change in DNA.</li>
	<li>They can pop up anytime, but it&#39;s usually rare. Think of DNA like your trusty old Nokia phone; it&#39;s super resistant!</li>
</ul>

<ul>
	<li>When is DNA most vulnerable? During replication!
	<ul>
		<li>Imagine copying your friend&#39;s notes, but accidentally scribbling an &quot;E&quot; instead of an &quot;A&quot; in the process. Oops!</li>
	</ul>
	</li>
	<li>Sometimes, DNA makes base-pairing errors during copying (replication).
	<ul>
		<li>Good news: DNA has its own spellcheck called DNA repair. Bad news: Sometimes, spellcheck misses stuff.</li>
	</ul>
	</li>
</ul>

<ul>
	<li>They&#39;re external agents that increase mutation chances.</li>
	<li>There are two main villains here: radiation and chemicals.</li>
</ul>

<ul>
	<li>Not all radiation is bad, only the ones with enough energy to mess with DNA.
	<ul>
		<li>Gamma rays: Super intense energy waves. If you&#39;ve ever had an X-ray at the dentist, you&#39;ve been exposed (in safe amounts)!</li>
		<li>X-rays: Yep, the same ones used in hospitals.</li>
		<li>Alpha particles: They come from radioactive stuff like radon. No, you can&#39;t see them, they&#39;re sneaky!</li>
		<li>Short-wave UV radiation: Think about a sunny day at the beach. Sunlight has this, so wear that sunscreen to protect both your skin and your DNA!</li>
	</ul>
	</li>
</ul>

Real-world example: Too much UV exposure can lead to skin cancer because of these mutations.

<ul>
	<li>Certain chemicals can also change our DNA.
	<ul>
		<li>Polycyclic aromatic hydrocarbons &amp; nitrosamines: Big names, right? They&#39;re found in tobacco smoke. Another reason to say no to smoking! 🚭</li>
		<li>Mustard gas: This nasty chemical was used as a weapon during WWI. Besides being harmful in many ways, it can mess with DNA.</li>
	</ul>
	</li>
</ul>

Real-world example: Smokers have a higher risk of lung cancer due to the mutagens in tobacco.

Mutations can be natural or caused by external villains like radiation or certain chemicals. While mutations might sound cool in comic books, in real life, they can lead to serious health issues. Always be cautious and take care of your DNA. It&#39;s the only set you have!
