Nucleic acids are the biolmolecules which are responsible for carrying information from one generation of organisms to the other. There are two types of nucleic acid namely the deoxyribo nucleic acid (DNA) and the ribo nucleic acid (RNA).
The similarity between the DNA and RNA is that both act as the genetic material carrying genetic information in them. Both are made up of polynucleotide chain with the repeating units called the nucleotides containing a nitrogenous base, a pentose sugar and phosphate. The difference lies in the type of the sugar and nitrogenous bases present. In RNA, the sugar is a ribose. In DNA, the sugar is a deoxy ribose derived from a ribose sugar by the loss of an oxygen atom. The nitrogenous bases of DNA are the adenine, guanine, thymine and cytosine. Whereas, the nitrogenous bases of RNA are the adenine, guanine, cytosine and uracil. Also, DNA is a double stranded molecule with two polynucleotide chains, whereas RNA is single stranded.
Receptors are needed for both Short and Long range cell signaling.
<h3>What are receptors?</h3>
In the cell, there are some special proteins who play the role of receiving external signals. These are what we call receptors.
These receptors could function for both long and short range cell signaling. Hence, Receptors are needed for both Short and Long range cell signaling.

Answer:
Buffy coat.
Explanation:
Between the plasma, and red blood cells the platelets, and white blood cells form a thin white layer which is known as Buffy coat following density gradient centrifugation of the blood.
Centrifugation is the process where the distinguish between cell fragments, and cell from the liquid intracellular matrix occurs. Centrifugation is a technique which separates the particles according to their size, density, viscosity and shape with the help of centrifugal force.
