RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.
The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.

The answer is; C & E
Building a dam alters the water regime down the dam. The dam also affects fish migration along the river, alters the transportation of sediments by the river downstream, and changes temperatures within the local environment of the dam. These changes, however, the subtle effect the ecosystem around the dam and down the river. The potential energy of the water held by the dam is, however, high and used to produce more electricity.
Explanation:
they include floodwalls/seawalls, floodgates,levees, and evacuation routes. Nonstructural measures reduce damage by removing people and property out of risk areas. They include elevated structures, property buyout, permanent relocation, zoning, subdivision, and building
Answer:
- Use bikes and non motor engines to get short distances BIKES is a good option.
- Support electricaly charged vehicles
- Turn off your car when you are not driving
- Walk to school if you can
- Make sure to recycle paper
- reuse old notebooks that are not finished for the next year
- Get outdoors and spread your carbon dioxide
- try playing ball games and not video games so much becasue it means you use electricity that is generated by fossil
- Turn off lights before bed
- dont keep the TV on all the time.
Explanation:
Hope that helps :)
