<ul>
	<li>Mutations are described as random changes. Imagine trying to predict the roll of a dice &ndash; it&rsquo;s just as tough predicting a mutation.</li>
	<li>Even if we&rsquo;re unsure about what &quot;truly random&quot; means, mutations are surely unpredictable.</li>
</ul>

<ul>
	<li>Nope! Organisms can&#39;t direct mutations to achieve a specific outcome. It&#39;s not like ordering your favorite pizza.</li>
	<li>There&rsquo;s no &quot;intentional&quot; mutation mechanism discovered in organisms. Think of it like trying to find a unicorn.</li>
	<li>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.</li>
</ul>

<ul>
	<li>Anywhere in the DNA! But, some DNA bases are more likely to mutate because they change chemically more easily.
	<ul>
		<li>Real-world example: Just like some ice creams melt faster under the sun due to their ingredients!</li>
	</ul>
	</li>
	<li>A DNA&#39;s position also affects mutation chances. How? Because coding DNA (that makes proteins) and non-coding DNA (like DNA punctuation) have different &quot;jobs&quot;, and that affects mutation rates.</li>
</ul>

<ul>
	<li>Usually not! Think of an artist&#39;s masterpiece that took years to create. If you randomly change a brushstroke, chances are it won&rsquo;t improve the art.</li>
	<li>Most random mutations are neutral or even harmful. Genes have been fine-tuned over long periods of time.</li>
</ul>

<ul>
	<li>No mechanism exists to &quot;test drive&quot; mutations during an organism&#39;s lifetime to only keep the good ones.</li>
	<li>If a mutation happens in a body cell, it might get expressed. But once the organism dies, so does that mutation.
	<ul>
		<li>Example: If you get a tattoo (a &ldquo;mutation&rdquo; to your skin), it doesn&rsquo;t mean your child will be born with the same tattoo.</li>
	</ul>
	</li>
	<li>Germ-line cells (like in human testes &amp; ovaries) are the game-changers. Mutations here can pass to the offspring, but they aren&rsquo;t &quot;tested&quot; in the body.</li>
	<li>So, even if you get a cool mutation in your lifetime that&rsquo;s beneficial, your kiddos can&#39;t inherit it unless it&#39;s in the germ-line cells. This explains a lot about how evolution works!</li>
</ul>

Remember: Nature doesn&rsquo;t have an agenda. Mutations are unplanned, often like spilling paint on a canvas. Some might make the artwork more interesting, while others... not so much! 🎨
