From DNA to protein – 3D


Here is a cell, the basic unit of all living tissue. In most human cells there is a structure called the nucleus. The nucleus contains the genome. In humans the genome is split between 23 pairs of chromosomes. Each chromosome contains a long strand of DNA, tightly packaged around proteins called histones. Within the DNA are sections called genes. These genes contain the instructions for making proteins. When a gene is switched on, an enzyme called RNA polymerase attaches to the start of the gene. It moves along the DNA making a strand of messenger RNA out of free bases in the nucleus. The DNA code determines the order in which the free bases are added to the messenger RNA. This process is called transcription. Before the messenger RNA can be used as a template for the production of proteins, it needs to be processed. This involves removing and adding sections of RNA. The messenger RNA then moves out of the nucleus into the cytoplasm. Protein factories in the cytoplasm, called ribosomes, bind to the messenger RNA. The ribosome reads the code in the messenger RNA to produce a chain made up of amino acids. There are 20 different types of amino acid. Transfer RNA molecules carry the amino acids to the ribosome. The messenger RNA is read three bases at a time. As each triplet is read, a transfer RNA delivers the corresponding amino acid. This is added to a growing chain of amino acids. Once the last amino acid has been added, the chain folds into a complex 3D shape to form the protein.

  1. So many tinies working so well. I'm so proud of them. They go to "work" and do there jobs, they breathe and excrete when needed. They help those around them to do better. All together to make something work.
    Hmm.. Wonder what would happen if a few of your tinies suddenly decided that they were more important and tried to lock themselves away in a tight group, cuz their way is better? Oh. Yeah. You call that cancer. Respect the tiniest because no matter how big you think you are, you are a tiny too.

  2. Religious people believing in God because they don't think science can explain this.
    "God of the gaps" is a theological perspective in which gaps in scientific knowledge are taken to be evidence or proof of God's existence.

  3. if we added the genome of sugar cane with ukyliptus trees or coconut then we got more sugar

    if we mixed the genome of mango tree with mustard plants then we got mango pickle automatically

    if we put genome of big trees pipal and oil produce plants seed then we got lots of oil every year

  4. It’s disappointing that people blow over the genius design of the DNA process and say “This obviously evolved”. I don’t think we want to believe that non living matter created living matter. Especially without any proof to support that claim.

  5. Doesn't the DNA exist as chromatin strands within the nucleus? Don't they only form chromosomes when the cell is about to divide?

  6. リボソームって大サブユニットと小サブユニットで伝令RNAを上下で挟み込むのか……
    知らなかった

  7. is it just me or does the lady narrating sound like the person who narrates the safety videos on long flights? just me? alrighty then

  8. This is clear evidence of Intelligent Design! How can a medium encode it's sequence with information and encode the instructions to build the machinery to decode this information? We do this all the time as intelligent beings. It's like saying a snowflake is encoded with information in it's sequence to build igloos and snowmen LOL! A natural interpretation of evolution is a FANTASY!

  9. How the molecules moved randomly by collision each others. Or shivering molecules, they are no muscle contraction. No direction to imagine

  10. この動画を試験が終わる前に見たかった

  11. When 'processing' how does the messenger know what bits of RNA to add/remove? That's almost sentient behavior…isn't it?

  12. I'm all for evolution and shit, but how's random chaos behaving in such a harmonic coordinated way. How it's possible each string follow certain said path and how the fuck do they recognize each other? Everything looks like logic, litteral organic nano-machines. God and science, going all back to it's primordial origin, nobody got a damn clue how and why. It really blows my mind.

  13. الجينات هى الشئ الحامل للموارث فى الصفات البشرية ولسائر المخلوقات …جينات الوراثة

  14. There´s no way this happens by chance, no way, information can only be arranged by a mind. Praise the Lord.

  15. Congratulations to the team that made this video.The animation provides an easy understanding to a much complex process! (Much better than the schemes in the old books 😃)

  16. Anyone who looks at this and doesn't see that this is intelligent design and that all life is amazing and mystical and sacred, doesn't deserve it.

  17. Hey i'm 15 years old from the republic of Korea
    Today i studied this whole process at the private school…
    Driving me nuts

  18. I'm getting bored with just being shown the workers in the factory doing their jobs. I want to interview the workers. I want to ask them how they learned to read. Why they work in the factory and where they learned their skills

  19. God…is…GOOD!!!!!! Wowwww!!!!😮

    Only fools can say…"nothing" created this larger then extraordinary piece of machinery!!!! 🤔😃

  20. There is no god but GOD…Prophet Mohammad (pbuh) is the last and final measenger of GOD….Jesus(pbuh) is also a mighty messenger of Almighty GOD……it is impossible this DNA code come by itself….information can not come without blind evolution….

  21. Who has programmed us? How these molecules know the way to connect to each other? Who's standing behide the reality?
