You have one single circular highway (their single chromosome), and the whole operation starts at just one specific spot. In bacteria like <i data-path-to-node=\"10\" data-index-in-node=\"215\">E. coli<\/i>, we call this starting block the <b data-path-to-node=\"10\" data-index-in-node=\"256\"><span class=\"math-inline\" data-math=\"oriC\" data-index-in-node=\"256\">$oriC$<\/span> region<\/b>. Because bacteria need to divide fast to survive, replication is <b data-path-to-node=\"10\" data-index-in-node=\"333\">bidirectional<\/b>. Picture two construction crews starting at that single <span class=\"math-inline\" data-math=\"oriC\" data-index-in-node=\"403\">$oriC$<\/span> point and driving away from each other in opposite directions, paving the track as they go until they meet on the other side.<\/p>\n<p data-path-to-node=\"11\">We can break this down into two main stages: <b data-path-to-node=\"11\" data-index-in-node=\"45\">initiation<\/b> and <b data-path-to-node=\"11\" data-index-in-node=\"60\">elongation<\/b>.<\/p>\n<ol start=\"1\" data-path-to-node=\"12\">\n<li>\n<p data-path-to-node=\"12,0,0\"><b data-path-to-node=\"12,0,0\" data-index-in-node=\"0\">Initiation:<\/b> The crew arrives at <span class=\"math-inline\" data-math=\"oriC\" data-index-in-node=\"32\">oriC<\/span>, unzips the double helix, and sets up the heavy machinery.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"12,1,0\"><b data-path-to-node=\"12,1,0\" data-index-in-node=\"0\">Elongation:<\/b> An enzyme called <b data-path-to-node=\"12,1,0\" data-index-in-node=\"29\">DNA polymerase III<\/b> acts as the main builder, matching incoming free nucleotides to the template strand using basic base-pairing rules (A with T, and G with C).<\/p>\n<\/li>\n<\/ol>\n<p data-path-to-node=\"13\">Now, let&#8217;s clear up a massive rumor right away. The original draft of this text claimed that prokaryotes completely skip out on proofreading and editing. That is actually a myth!

Both prokaryotic and eukaryotic replication are completely <b data-path-to-node=\"37,0,1,0,0\" data-index-in-node=\"78\">semi-conservative<\/b>. To understand what this means, imagine you have a classic family recipe book. Instead of copying the whole book from scratch, you split the book in half, keep the original pages on the left, and write down matching updated pages on the right. Every new DNA molecule is a hybrid: one old parent strand and one shiny new daughter strand.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<li>\n<p data-path-to-node=\"37,1,0\"><b data-path-to-node=\"37,1,0\" data-index-in-node=\"0\">Misconception 2: Eukaryotic replication only moves in one direction.<\/b><\/p>\n<ul data-path-to-node=\"37,1,1\">\n<li>\n<p data-path-to-node=\"37,1,1,0,0\"><i data-path-to-node=\"37,1,1,0,0\" data-index-in-node=\"0\">The Reality:<\/i> Actually, it is bidirectional.

To do this, they cannot just wish it into existence\u2014they have to copy and paste the genetic code.
