A cell contain a description in its genome of all it has learned about
survival.
A cell contain a description in its genome of how to construct an
organism that can survive long enough to perpetuate a genome.
A cell contains a description in its genome of the mechanisms that can
adapt a nervous system to an unknown milieu. These mechanisms include
the capability of axonal growth, and the creation of synapses. Of the
strengthening and weakening of synapses. Of the release of
neurohormones that signal that recently exercised synapses should be
strengthened after an event. The strengthened synapses constitute a
memory and learning.
Which events should be remembered?

No, cells live far less long - a few (tens of) years at max.
You probably mean the cells evolution as a whole. But today's cells have
nothing in common with 3.5b years ago's cells, which were much more
primitive.

No, the amount of data encoded in DNA is too limited for that. Plus as
of today's knowledge, there's no learning system that alter the DNA to
encode information. DNA data is just the result of chaotic evolution.

Ok ; if precising there's no active purpose or will.

Who knows...
PS: I think you're overestimating the system that creates organs from
cells and that makes our body grow and live. It doesn't have its own
will on what to remember, on what's the best way to alter a nerve
system... It just happen to do whatever set of chemical reactions it's
to do.

The human species _IS_ a learning machine which records its lessons learned
in the DNA. It's working just fine today as it was a million years ago.
True, not everything learned remains encoded in our DNA, but I don't
believe that was Ray's point. He just meant that the result of all that
learning, is what is encoded in our DNA (and in the design of the cell that
uses the DNA but most people seem to leave that half of the equation out).

We tend to remember events that we found rewarding and thus
worth trying to get to happen again and events that we found
punishing which we try to prevent from happening again.
We should keep in mind there are different types of memories.
Humans can break continuous time into events which we can
manipulate the way we manipulate objects but our older systems
simply change their connections as a result of "events" without
the events themselves, as events, being remembered.
You can train a goldfish to swim to the surface to be fed at
the sound of a bell but the fish will not remember any of the
individual events that occurred previously that brought about
that change just as you probably don't remember the first time
you learned any of the words you are now reading.

To start off, we set aside all discussion about what it means to say
that one group of molecules is alive, and another is dead.
Mitosis (and meiosis) does not create life, it divides life. Every
living cell today was alive at the beginning, it is 3.5 billion years
old.. Again, we put to one side all arguments about the beginning.

The genome is what it is. You are welcome to speculate that it could
have been more. It is enough as it is. .

Purpose and will belong to the religionists.

Short answer: Ask anyone you chance to meet in the street. Long
answer: Any event that caused trauma.

Oh, Lord! I do try. Notice that you refer to an “it”.

But is not human will the same thing? Just a chemical reaction that "it's
to do"?
So why is it ok to talk about the chemical reaction of a human body as
"will" but not talk about other chemical reactions as "will"?
