Thus DNA replication is a form of semi-conservative replication because each DNA has one strand belonging to the parent and one new strand. She also elucidated the basic helical structure of the molecule. • DNA polymerase cannot synthesize the extreme 5’ end of the lagging strand • RNA primer cannot be replaced with DNA at the 3’ end of the DNA template • In the absence of a mechanism for completing the lagging strand, linear chromosomes would be shortened at both ends by at least the length of an RNA primer with each round of replication In conservative replication, the parental DNA remains together, and the newly formed daughter strands are together. DNA stands for deoxyribonucleic acid and carries the genetic information in all types of living organisms. DNA replication is semi-conservative one strand from each of the initi DNA replication, also known as semi-conservative replication, is the process by which DNA is essentially doubled.It is an important process that takes place within the dividing cell. DNA Structure & Replication. Each body cell gets acomplete set ofidentical DNA. DNA has a double-stranded helical structure with the backbone made of sugar and phosphate. They unzip like a zipper using DNA Helicase (enzyme) Each strand then builds its opposite strand by base pairing with nucleotides that float freely in the nucleus. Created: Jun 21, 2011.

DNA is a double-helix, composed of a backbone chain of deoxyribose sugar, phosphate groups, and four nitrogenous bases. DNA replication: ¥Complementary base pairing produces semiconservative replication ÐDouble helix unwinds ÐEach strand acts as template ÐComplementary base pairing ensures that T signals addition of A on new strand, and G signals addition of C ÐTwo daughter helices produced after replication. A single strand of DNA serves as a template for a new strand. The molecular structure of DNA was described by Watson and Crick.
