A. RNA is regarded as the reserve of genetic information.
B. DNA molecule self-duplicates during cell division.
C. DNA synthesizes proteins in the cell.
D. The message for the synthesis of particular proteins is present in DNA.
E. Identical DNA strands are transferred to daughter cells.

Checking statements about nucleic acids:

A. RNA is regarded as the reserve of genetic information — FALSE (DNA is the genetic reserve).

B. DNA molecule self-duplicates during cell division — TRUE.

C. DNA synthesizes proteins in the cell — FALSE (RNA/ribosomes synthesize proteins).

D. The message for synthesis of particular proteins is present in DNA — TRUE.

E. Identical DNA strands are transferred to daughter cells — TRUE.

Correct statements: B, D, E = 3.

Therefore, the answer is $$\boxed{3}$$.
