It&amp;#x27;s always amazing to watch what is in practice a molecular-sized machine:&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=OjPcT1uUZiE&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=OjPcT1uUZiE&lt;/a&gt;</text></comment>

These animations always just show them appearing in perfect sequential order when they&amp;#x27;re needed, which is of course not what happens.&lt;p&gt;How are they delivered to the polymerase in the first place? How do they &amp;quot;know&amp;quot; where to be?&lt;p&gt;Are there just so many of them in the cytosol that through sheer numbers, there&amp;#x27;s enough random chance they&amp;#x27;ll just shuttle into place when the polymerase needs them?</text></comment>
