Close-Up View of DNA Replication
Something I&#x27;ve never understood is how the nucleotides arrive to be included in the DNA strand. These animations always just show them appearing in perfect sequential order when they&#x27;re needed, which is of course not what happens.<p>How are they delivered to the polymerase in the first place? How do they &quot;know&quot; where to be?<p>Are there just so many of them in the cytosol that through sheer numbers, there&#x27;s enough random chance they&#x27;ll just shuttle into place when the polymerase needs them?
