Biology Questions

In this blog post, I am going to collect links which shed light on various biology questions that have crossed my mind.


  1. Does a blood transfusion change your DNA?
    Answer: No, because "red" blood cells don't have DNA

  2. I think cells in our body are Eukaryotes (cells which contain complex structures enclosed within membranes) but since red blood cell don't contain DNA, could they be Prokaryotes (cells which lack a cell nucleus (karyon), or any other membrane-bound organelles.) ?
    Answer: Every single cell inside our body is eukaryotic. Red blood cells lose their nucleus during maturation.
