DNA is much like computer code, and cells are much like computers.

Not like any computer ever built or programmed by humans. If the analogy were even remotely correct, computers would build their replacements from raw materials, and they would adapt to changing conditions.

"DNA is much like computer code, and cells are much like computers."

"Not like any computer ever built or programmed by humans. If the analogy were even remotely correct, computers would build their replacements from raw materials, and they would adapt to changing conditions."

I guess that would be the difference between "Exactly Like" and "Much Like".

And like you indicated correctly that it was an analogy, which is not an exact description.
