PPT-Cell cycle, DNA, and replication

BIO LIFE THINK ABOUT THIS What do we do in our lifetime What are the major stages of our life What are the Major stages of physical development in our lives What would it look like. Models of DNA replication: Meselson-Stahl Experiment. DNA synthesis and elongation. DNA polymerases. Origin and initiation of DNA replication. Prokaryote/eukaryote models (circular/linear chromosomes). Chapter . 7.2. Processing of Genetic Material. What is DNA Replication. The process by which the DNA within a cell makes exact copies of itself. Balance of speed and accuracy. Used for growth, repair and embryonic development. Learning Objectives. What happens during DNA replication?. How is a new polynucleotide strand formed?. Why is DNA replication known as ‘semi-conservative’?. Putting What We’ve Learnt So Far In To Context.... Objectives:. 1. Summarize the roles of the different enzymes involved in replication of DNA.. 2. Explain how the leading and lagging strands are replicated differently . Semiconservative. Replication. The function of DNA in the cells is to. preserve genetic information.. transfer genetic information to new cells as the strands of DNA are copied.. DNA Replication. In . DNA replication. ,. the strands in the original or parent DNA molecule separate to allow the synthesis of complementary DNA strands.. Semiconservative vs. Conservative. DNA Polymerase. RNA Primase.

DNA: Structure & Replication. In . their 1953 announcement of a double helix structure for DNA, Watson and Crick stated, . "It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.". Mitochondrial DNA replication.
