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:
agriculture can cause problems such as less housing, cut down of trees to make way for more agricultural things and the animals causes more droughts. But it helps give people food
Explanation:
Answer:
DNA polymerase
Explanation:
DNA polymerase is the enzyme that matches and lays down nucleotides to build the daughter DNA strand along each parent DNA strand.
Answer:
B
Explanation:
Because of the elk and other herbivores have increased and nothing is preying on them, they will overgraze.
Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting
