<span> RNA was thought of as little more than a messenger between DNA and proteins, carrying instructions as messenger RNA (mRNA) to build proteins. However, RNA can do far more. It can drive chemical reactions, like proteins, and carries genetic information, like DNA. And because RNA can do both these jobs, most scientists think life as we know it began in an RNA world, without DNA and proteins.</span>
Perhaps the best known unconfined aquifer is the Ogallala. In many places this aquifer is near the surface and recharge depends on water that collects at the surface in wetlands. ... A playa lake is a naturally occurring wetland (averaging about 17 acres) formed when rain fills small depressions in the prairie.
