Crick’s hypothesis is true. Information as present in DNA is passed on to RNA to protein (this is biology so of course there are exceptions). What is not true is that the sequence is primary or the material is secondary. Crick never said that, and the chemistry, physics, and structure involved was of great interest to him, so his hypothesis does not support your contention.
Agreed, it functions as part of a biochemical process.
For any given subsequent generation of organisms, the distribution of change is small.
