A) parent cell enlarges and duplicates all its genetic material. B) DNA copies move to opposite ends of parent and attach to a section of the cell membrane as it begins to pinch together at the center. A. Structure of DNA. 1. discovered by James Watson and Francis Crick in 1953. 2. stores genetic information for the production of proteins. 3. composed of nucleotides. A) a nucleotide is composed of a nitrogenous base, sugar, and phosphate. Stream Ecology. 1/22/2009. Stream Load Classifications. Bed load. : Sediments moving predominantly in contact with or close to the stream bed.. Suspended load. : Sediments that move primarily suspended in fluid flow but may interact with bed load and is comprised primarily of silts and clays and sometimes sand. Suspended load has a continual exchange between sediment in fluid flow and on the bed as it is constantly being entrained from the bed and suspended while heavier particles settle out from the flow to the bed. .
