The secondary structure is responsible for the shape that the nucleic acid assumes. The bases in the DNA are classified as purines and pyrimidines. ... A purine base always pairs with a pyrimidine base (guanine (G) pairs with cytosine (C) and adenine (A) pairs with thymine (T) or uracil (U)).

-Suspension
Cells not dissolve in blood but they form a suspension because they do not settle out of the blood either
Explanation;
-Blood is a solution of salts, glucose, urea and a few other small compounds. It's a colloid of plasma proteins, including albumin, transport proteins and antibodies. It's also a suspension of blood cells and platelets.
-Suspensions and colloids are two common types of mixtures whose properties are in many ways intermediate between those of true solutions and heterogeneous mixtures. A suspension is a heterogeneous mixture of particles with diameters of about 1 µm (1000 nm) that are distributed throughout a second phase.
-Common suspensions include paint, blood, and hot chocolate, which are solid particles in a liquid, and aerosol sprays, which are liquid particles in a gas.
