  • @kumbiraideon5505
    @kumbiraideon5505 7 ปีที่แล้ว +13

    This is wonderful. Thank you for a simplified version of translation. Sometimes i prefer watching these summarized videos than reading a book..But i got a question in relation to the 'E, P, A' sites how is it possible that we have an Exit on the 5' yet the mRNA is run thru the ribosome from 5' 3' direction ..Can you assist on that maybe i missed it

    • @AdaTrimaj
      @AdaTrimaj 7 ปีที่แล้ว +2

      I think it is a mistake, the 5-3 direction should be opposite in that video to make sense. Evrything else seems to be okay.

    • @thepsychhike7177
      @thepsychhike7177 5 ปีที่แล้ว +8

      its not a mistake. the E site is on 5' bc the ribosome is moving towards 3' but the codons are still at the same place. so the tRNA which is initially on p site shifts to the E site not bc it is moving towards 5' end but bc the ribosome is moving towards 3' end and the tRNA is still in its position.
