Genes Have Play, Stop and Pause Buttons

You probably remember from biology class that genes hold information that is used to construct protein and RNA molecules which do various tasks in the cell. A gene is copied in a process known as transcription. In the case of a protein-coding gene the transcript is edited and converted into a protein in a process known as translation. What you may not have learned is the elaborate regulatory processes that occurs before, during and after this sequence of transcription, editing and translation.  Read more

  1. A gene is copied in a process known as transcription.

    A (specified) sequence of DNA is transcribed into a complementary sequence of RNA via a process known as transcription.

  2. It boggles my mind that any intelligent person can read Hunter’s whole article, which only lays out a small fraction of the machinery and operation of the cell, and believe that this incredibly intricate and sophisticated system could possibly have arisen by Darwinian processes. It’s simply preposterous. Come on, people, get a clue!

  3. Dr Hunter:

    A good 101 survey of regulatory and control loops in the cell and between cells, even including food.

    Anyone who has had to tune a regulatory loop or two will know that the functional complexity and specificity of such things has long since shot through the roof.

    As in, yet more empirical pointers to the reality of the much despised islands of function . . .

  4. Hilarious last paragraph of Cornelius! Two wicked ‘put downs’ by any standards in two days, with W J Murray starring on here, yesterday.
