    thank you for this video, i can now understand topic 6 now, i just now need to go over all of it now.
    But could i ask a question?
    So lets say my hand for example, made up of a bunch of skin cells, which all have a nucleus and DNA for protein synthesis. So one skin cell in my body is programmed to create specific chain of amino acids to make a protein, now will my all my skin cells on my hand produce different chains of amino acids or would they all produce the same exact chain of amino acids? or will they produce different amino acids every different cell?

      Thanks Adham! Basically, all of your skin cells will produce a similar set of proteins. So there will be some proteins that all of them make (by coding for the exact same sequence of amino acids), and other proteins that only some of them make, depending on what type of skin cell they are (you don’t need to know about the different types).
      When they produce the same protein they will use the same amino acid sequence to do it.

      Hope that helps πŸ™‚
