The overall unzipping process is in one direction, from the bottom of the diagram up to the top. \u00a0However, there are 2 chains. As the new DNA chains only grow in the 5′ to 3′ direction they must grow in opposite directions.<\/p>\n
The 2 strands of the original DNA molecule run in opposite directions.<\/p>\n

The deoxyribose sugar is a 5carbon sugar. Each of the carbon atoms in the sugar is given a number. These 5 carbon sugars are connected by phosphates and the end that finishes with carbon 5 exposed is the 5’end, the other is the 3′ end. In reality each sugar has a base attached so we have a chain of nucleotides. A complete DNA molecule is a double helix with the two strands running in opposite directions.<\/p>\n
The incoming nucleotide units can join only to the exposed 3′ end thus a new DNA chain can grow only in the 5′ to 3′ direction. The strand that has its 5’end exposed is called the leading strand and grows continuously, towards the\u00a0replication\u00a0fork. The other strand (lagging strand) cannot start from the exposed 3′ end so instead it starts growing from a carbon 5 at the fork. It then grows away from the \u00a0fork toward the 3′ end. As the fork unravels, exposing more bases, another Okazaki fragment starts forming at the fork and grows toward where the previous Okazaki fragment started from. When they meet they join up to eventually form a single lagging strand.<\/p>\n
