Video: From DNA to Protein

DNA is expressed and put into action through proteins. These proteins are involved in structural support and they also act as enzymes. Enzymes are involved in all of the chemical reactions that happen in the body. In this lecture, I first talk about the relationship between DNA and Protein and how this relationship leads to all of the traits that an organism expresses. I then go into the differences between DNA and RNA.

Transcription is the process that results in the production of mRNA. Translation ultimately results in the production of proteins. Understanding these to processes is essential to our understanding of how DNA is the Blueprint of Life.

This is part Chapter 11 in the textbook Biology: The Dynamics of Life, which is the chapter on DNA and Genes.

    Thank you once again as you have managed to help me complete my flow chart on transcription & translation. I like listening to your lectures which are so much better than the lectures we get, please come to Cornwall in England to teach the tutors how to teach properly!!!!

      LOL, I would LOVE to visit Cornwall in England. Just send me a ticket :D

      Glad to know that you are finding so much value in the videos :)

    Hi Leslie! First and foremost, I want to tell you how much I appreciate your videos and lectures. You have made learning about Biology fun! Your sight is the first I visit to gain a better understanding of whatever it is that I am learning. God has blessed you with an amazing talent to teach. Keep up all of your great work!
    Second, I am looking to gain a better understanding of transciption and translation. I was trying to pull up the video that you have listed for this, howeve it was not working. Do you still have this video available? Thank you so much.

      Hi Sadie,

      First off, thank you for your compliment. I really appreciate it.

      Sorry about that, I was doing some work on the backend of my site and that turned off the video. I’ve fixed it and you should be able to watch it now.

      All the best!

    Hey thank you so much,I know most teachers don’t approve of cramming a day before a test but they haven’t come across your website. I only one problem i cant seem to view your video on DNA to protein. PLEASE HELP
    Thank You

      I’m sorry but it’s not available at the moment. I have to eventually go through and try to retrieve some of these older videos.

    Hi, I have just emailed about the mutations video which I can’t open on my laptop and the same has happened on all the other videos in the ‘genetics’ section on this site. I’m not sure whether it’s a problem on my laptop or that the videos are not uploaded properly? I just get a load of script at the top of the page.

    In eukaryote’s transcription some introns are spliced using snrnp’s
    Are these snrnp’s / snurps a ribozyme or not

    I just found your website – wow! I’m a mature student and only started biology this year. As you can imagine, it can be overwhelming! I’m trying to understand transciption and translation. I was trying to pull up the video that you have listed for this, however it was not working. Do you still have this video available?
    I’m from South Africa :)

    Dear Leslie,

    Hello. I would really like to watch these videos but, I feel that they are not working or perhaps are no longer available. Could you please re-load them again, We would be indeed delighted and obliged too.

    Thanks and warm regards,

    Mr. K P Faarokh
