    In the video it is said that each of the cells has “a different genetic code”.

    Hmm. I though that all of them, in their nuclei, use the same genetic code, the Universal code.

    It seems that the writer of the video does not know what a “genetic code” is.

    Enjoyable. Reminds me of Lewis Thomas’s “Lives of a Cell” stuff.I like the comment at the end about continua v. black & white.

    James Shapiro thinks cells are sentient beings.

    Bacteria as natural genetic engineers….

    This remarkable series of observations requires us to revise basic ideas about biological information processing and recognize that even the smallest cells are sentient beings.

    James Shapiro

    Well, I don’t think so, or at the very least I haven’t had a conversation with a cell that persuaded me that it was sentient.

    There is no organic or inorganic entity that has a nature. Any materialist/naturalist denies essences. The nature of us is a meaningless question.

    People here at TSZ don’t know what a “genetic code” is. Why not enlighten everyone and tells us?

    Immediately suspect is the claim that cells have no purpose. But that simply must be true, because there is no purpose for anything, not even cells.

    But in the next breath the narrator goes on to list a number of things that cells gather together in order to accomplish.

    Is it possible then that some cells could gather together for the purpose of identifying self-refuting nonsense? Nah, that’s just silly.

    As everyone here at TSZ knows, there is no such thing as a self-evident truth, and the absence of any self-refuting nonsense is an important pillar for that position.

    The narrator claims that “your cells” can exist “without you.”

    It is no doubt just this sort of claim that Richardthughes had in mind when he prayed to the gods that his OP would start a lively discussion. I think he forgot who his audience is. If they exist without you, then they are not your cells.

    It doesn’t take a genius.

    The narrator claims that “your cells” can exist “without you.”…If they exist without you, then they are not your cells.

    Sure they are. Your liver cells, functioning in vitro, are still your liver cells. Your DNA, found in your cells at a crime scene, is still your DNA.

    Are you disputing the narrators comments that each neuron cell in the brain has around 1000 mutations that are not the same as the cells next to it?

    Furthermore how can a lung cell have the same code as a liver cell, if they are not the same?

    Maybe its you who doesn’t know what a code means?

    The genetic code they use is the same. The sequences of DNA they have are different. See the difference?

    During development cells differentiate and become tissue specific. This is a process where non tissue specific DNA gets turned off (methylation). The type of cells where multi tissue cells DNA is turned on are called stem cells.

    Yes.

    But what I can’t understand is the exact same Morse code message which means either “I am in trouble, please send help” or “This place is great, bring some more beer, the party is on.”

    keiths,

    Again, if you are having trouble getting the distinction keith, it is this:

    How can the exact same code, written by the exact same machine, and interpreted by the exact same machine, give different results for the exact same code? Is it the code that is different or the machine that is different?

    First things first, phoodoo.

    Let’s clear up your confusion over the difference between genotypes and the genetic code.

    Different messages can be expressed using the same Morse code, just as different genotypes can be expressed using the same genetic code.

    Are those distinctions clear to you?

    It depends on whether you are reading the first paragraph of the encoded message, or the second paragraph.

    Neil,

    Who is deciding which paragraph to read? Don’t you need a code to create the organism which decides which code to read?

    phoodoo,

    Have you ever considered learning some biology?

    Wikipedia:

    In developmental biology, cellular differentiation is the process of a cell changing from one cell type to another. Most commonly this is a less specialized type becoming a more specialized type, such as during cell growth. Differentiation occurs numerous times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover. Some differentiation occurs in response to antigen exposure. Differentiation dramatically changes a cell’s size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics. With a few exceptions, cellular differentiation almost never involves a change in the DNA sequence itself. Thus, different cells can have very different physical characteristics despite having the same genome.

    There’s more where that came from. LMGTFY.

    You seem to think you are saying something. Yet, we still haven’t answered what is deciding to read which paragraph (epigenetics). If you don’t have a code somewhere that tells the epigenetics what to do, how does it know what to do? Why doesn’t your epigenetic system tell your head to turn into a horse liver? (Perhaps it does?)

    Epigentics has no code??
