Well, this is a gross oversimplification due to the fact only 60% of a specific part of our genome is shared with it, but it's part of the basic "system 32" part of our DNA that lets us live
Specifically for the part of our DNA that lets complex multicellular land creatures exist
And yes that sounds incredibly strange but friendly reminder that applies to every single plant, not just bananas
Even though animals came before plants, we still share plant DNA (if you're a land creature, that is)
