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.". Genetic engineering involves inserting foreign genes or modifying the activity of existing genes. . This technology exploits the process of gene cloning which involves making many identical copies of a gene. . RNA. RNA. Protein. Protein. Scientists call this the:. Central . Dogma. of . Biology!.

Griffith finds a ‘transforming principle.’ . Griffith experimented with the bacteria that cause pneumonia.. He used two forms: the S form (deadly) and the R form (not deadly).. A transforming material passed from dead S bacteria to live R bacteria, making them deadly.. . What is DNA?. DNA is a . Nucleic Acid in the nucleus. Polymer of . Nucleotides.
