In the decay process: A overset(- alpha)rarr B overset(-beta)rarr C overset(-beta)rarr D

In the decay process: A overset(- alpha)rarr B overset(-beta)rarr C overset(-beta)rarr D

Identify [A] and [B] in the following ""_(89)^(227)Acoverset(-beta)rarr[A]overset(-alpha)rarr[B]overset(-alpha)rarrRn

What is meant by DNA overset(a)(rarr) RNA overset (b)(rarr) Protein?

(i) A radioactive nucleus 'A' undergoes a series of decays as given below : A overset(alpha)rarr A_(1) overset(beta)(rarr)A_(2)overset(alpha)rarrA_(3)overset(gamma)(rarr)A_(4) . The mass number of atomic number of A_(2) are 176 and 171 respectively. Determine the mass and atomic numbers of A_(4) and A. (ii) Write the basic nuclear processes underlying beta and beta^(-) decays.
