Write An Essay On Dna Intertwining

According to Science Alert.com, DNA is a double helix which consists of two intertwining strands of genetic material and this genetic material is made of four different bases which are guanine, thymine, cytosine and adenine. (1) Replication occurs when an enzyme called helicase uncoils into the double helix onto two intertwining strands. The second enzyme is called primase and basically what this does is it attaches a ‘primer’ to each of the strands and the third enzyme is called DNA polymerase and this attaches to the primer and adds new bases to form the new double helix. “Double helices are formed from two strands running in opposite directions”, (2) meaning that there is a stand called the ‘leading strand’ and this stand is the strand that winds around first and secondly the other strand involved in this process is the ‘lagging strand’ and this strand follows the leading strand. Finally the new genetic material that is attached during replication matches the original. Into further explanation, the leading stand detaches and the enzyme adds bases that are identical to the lagging strand and when the lagging strand detaches the new material that comes from it is identical to the

So the lagging strand would stopped synthesizing, the leading strand would continue to grow. Also there were cases where one strand could start replicating 10 times its original speed for no reason. After all this experimentation, Kowalczykowski states,” We’ve shown that there is no coordination between the strands. They are completely autonomous.” So concluding all of this, the researchers found that because the lack of some of the strands not being a match, the DNA double helix came into play and stop the help case from uncoiling any further so that the polymerase had time to reach the
