Life as we know it depends entirely on the capacity of cells to utilize energy and molecules in the environment for cellular function and reproduction. . One of the benefits of the double stranded DNA structure is that it lends itself to repair, when structural damage or replication errors occur. Several kinds of chemical change may cause damage to DNA:. . REPLICATION – GENERAL PRINCIPLES. START. Must be ready . Must know where to start . FINISH. Must all finish . Must ensure that each piece of DNA is replicated only once . Therefore must know where to finish . By: Michelle Rivera, . eSmirna. . cantu. , Alexa Campos. What are pesticides?.
