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.

Answer:
B
Explanation:
The right lymphatic duct drains the right side of the head, neck, and chest wall; it also drains the right lung and the lower half of the left lung, the heart, the dome of the liver, and the right diaphragm via the bronchomediastinal trunk.
Answer: It is not healthy.
Explanation:
Wearing a hat shields your eyes from the sun, which can cause your retinas to burn, this is why sunglasses are also recommended, it helps stop too much light from entering your eyes, as well as UV rays.
Wearing sunscreen can protect your skin from harmful sun rays. These harmful sun rays can cause skin cancer by putting a protective layer over the skin.
