Humans apparently share 50% of their DNA with bananas. We can all see the genetic differences but how do the similarities manifest themselves?

All multicellular organisms need to do some basic things like divide cells, have all the parts of cells, have cells stick to each other, decide how each new cell will function. For example, we all have structures in our cells called ribosomes that help make new proteins. The ribosomes of humans and the ribosomes of bananas do pretty much the same thing (even using the same code instructions for how to make new proteins).

The basic building blocks of cells are the same, with minor changes. So, the basic genetic code for these things is the same, with minor changes.
