Synizesis

Okay, so imagine you have some playdough, and you squish it between your fingers. When you do this, the playdough gets longer and thinner, like a snake.

Now, let's talk about something called synizesis. This is when tiny little strings inside of your body, called chromosomes, get squished and pulled just like the playdough.

Inside every cell in your body, you have chromosomes. They're kind of like a recipe book for how to make you. They're really important! So during synizesis, the chromosomes get squished and pulled so they can line up in a certain way.

Why is this important? Well, when your body makes new cells, it needs to make sure that each new cell gets a complete copy of the recipe book (chromosomes). If the chromosomes didn't line up right, the new cells might not have all the right instructions, and things could get really messed up!

So, synizesis is basically like a little dance that the chromosomes do to make sure they're lined up just right before the new cells are made.
