Okay kiddo, today we're going to talk about something called "bcl-2 homologous antagonist killer!"
Now, every living organism has tiny little things called "cells" inside of them. These cells are kind of like little factories that do important jobs for our bodies to keep us healthy and alive. But sometimes these cells get damaged or old, and they can become unhealthy or even dangerous.
That's where bcl-2 homologous antagonist killer comes in! It's a special protein that helps keep these unhealthy cells from causing problems. When a cell is old or damaged, it needs to be removed from the body so it doesn't hurt the healthy cells around it. But sometimes, these cells don't want to die and they won't go away on their own.
That's where bcl-2 homologous antagonist killer comes in. It's like a superhero that comes in and fights the bad cells, making sure they get removed from the body. It does this by telling the cell to go through a process called "apoptosis", which is kind of like the cell committing suicide.
So, to recap, bcl-2 homologous antagonist killer is a protein that helps our bodies get rid of unhealthy cells by telling them to commit suicide. It's like a superhero that keeps us healthy and strong!
