Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause

PROJECT 802 LAN STANDARDS The IEEE 802 Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet‚ 802.11 Wi-Fi‚ 802.15 Bluetooth/ZigBee‚ and 802.16. All the 802.11 specifications use the Ethernet protocol and Carrier Sense Multiple Access with Collision Avoidance

chromosome within a cell. The process‚ in its totality‚ is a sequence of three basic steps: initiation‚ elongation‚ and termination. To understand the process of DNA replication‚ you much first be familiar with the structure of DNA. Resembling a twisted ladder or a zipper‚ DNA is a double helix formed with nucleotides (structural units of DNA containing a base‚ a sugar‚ and one or more phosphates)‚ a phosphate and sugar backbone‚ and nitrogenous bases. There are four bases‚ and each one will only
