- 864: Information About Transgenic Organisms
- ... as the organism's own genes. The transgenic condition is achieved by injecting the foreign gene into the fertilized egg or into embryonic cells. The injected gene becomes part of the host cell's deoxyribonucleic acid (DNA) within the chromosome and is then inherited by all the cells produced during embryonic development. It is thus present in all the cells of the resulting adult organism and is inherited by all its ...

- ... stone is not preferred because the sharp edges can injure the root system. The sterilizing process is an easy, but a long and tedious job.

Flush the gravel thoroughly with fresh water. Add a fresh solution ...
- 866: Hydrologic Cycle
- ... water vaporizes into the atmosphere from vegetation, soil, lakes, rivers, snowfields and oceans-a process called evapotranspiration. As the water vapor rises it condenses to form clouds that return water to the land through precipitation: rain, snow, or hail. Precipitation falls on the earth and either percolates into the soil or flows across the ground. Usually it does both. When precipitation percolates into the soil it is called infiltration when it ...

- ... hurricane with maximum sustained winds of 80 mph. As of 8:00 AM EDT, the system was located about 210 miles east-northeast of Barbuda in the northern Leeward Islands. Some of Floyd's outer rain bands were already over part of the islands. Data from Air Force Hurricane Hunters flights indicated Floyd was strengthening and was forecasted to intensify to a Category III hurricane with maximum sustained winds of 115 ...

- ... and is now jointly researched by the DOE and the National Institute of Health (NIH). Research on the project began in 1990. They used a four-letter system to decode the long strands of deoxyribonucleic acid. As understood from previous research, there are four nitrogenous base pairs that make up DNA. A stands for Adenine, which is paired with T for Thymine, and G stands for Guanine, which is paired with ...
