Turkic and Chuvash are Altaic languages; Akkadian is a Semitic
language. The relationship between Altaic and Semitic languages is
very ancient, at least. Furthermore, it is very likely that the
Akkadian and Turkic-Chuvash roots for "do" are different and have no
relation to one another. Also, many languages have more than one
verb that can be translated as English "do" (and the English verb is
ultimately derived from either the PIE root for "give" or the root
for "put"). English "do" has a very general and vague meaning, so it
can be used to translate verbs of other languages that often have
more specific semantics.
With all due respect, I think you're looking for inter-language
connections where none exist.
