Hey future biologist! Ready to unravel the secrets of life itself? Let&#39;s dive into the DNA (Deoxyribonucleic Acid) world. Think of it as the instruction manual that guides all the living things on Earth. 🌍

DNA looks like a twisted ladder, and it&#39;s known as a double helix. Picture two snakes wrapping around each other, and you&#39;ll get the idea!

These strands are like two parallel lines, but they run in opposite directions. That&#39;s why they&#39;re called antiparallel.

<ul>
	<li>One strand ends with a phosphate group (like a tiny hat 🎩).</li>
	<li>The other ends with a deoxyribose sugar (a sweet treat 🧁).</li>
</ul>

If they didn&#39;t run in opposite directions, they wouldn&#39;t be able to form hydrogen bonds. Think of trying to shake hands but your arms are twisted around! Awkward, right?

DNA has a helical shape, like a curly fry. The constant diameter of this shape is 2 nanometres (2nm). Imagine the width of a human hair, and then think 50,000 times smaller!

Ever zipped up a jacket? That&#39;s how DNA&#39;s double helix looks! The zipper&#39;s teeth are like base pairs, and the two sides of the zipper are the antiparallel strands. Next time you zip up, think about DNA&#39;s fantastic dance party!

DNA is like a dance floor where nucleotides are partying in a very particular order. They form the basis of all life, and understanding their structure helps us in everything from crime-solving to treating diseases. Now, that&#39;s a party you&#39;d want an invite to!

Happy studying! 🎓🧪🔬

<ul>
	<li>Nucleotides: The building blocks of DNA.
	<ul>
		<li>Deoxyribose sugar: The backbone, it holds everything together.</li>
		<li>Phosphate group: The connecting link between sugars.</li>
		<li>Bases: There are 4 cool ones here:
		<ul>
			<li>Adenine (A)</li>
			<li>Cytosine (C)</li>
			<li>Guanine (G)</li>
			<li>Thymine (T)</li>
		</ul>
		</li>
	</ul>
	</li>
</ul>

<ul>
	<li>A dances only with T (they&#39;re exclusive!).</li>
	<li>G has eyes only for C.</li>
</ul>

These pairs are held together by something called hydrogen bonds. They&#39;re like the magnetic pull between two BFFs.

<ul>
	<li>2D Drawings: Like flat sketches of a 3D object.</li>
	<li>3D Models: Represent the full shape and all details.</li>
</ul>
