DNA Replication Animation – Super EASY

DNA Replication Animation – Super EASY

In this animation, we’ll see the remarkable way our DNA is tightly packed up, so that 6 feet of this long molecule fits into the microscopic nucleous of every cell. The process starts when DNA is wrapped around special proteins molecules called “Histones”. The combined loop of DNA and protein is called a “Nucleosome”. Next, the nucleosomes are packaged into a thread. The end result is a fiber known as “Chromatin”. This fiber is then looped and coiled yet again. Leading finally to the familiar shapes known as “Chromosomes”, which can be seen in the nucleus of dividing cells. Chromosomes are not always present. They form around the time cells divide when the two copies of the cell’s DNA need to be separated. When DNA replicates, its strands are separated by the enzyme Helicase. Single stranded DNA binding proteins keep the strands from reanealing One DNA strand encodes the leading strand, which forms from its 5′ to its 3′ end. Using DNA polymerase III. No problem here, but the lagging strand presents problems. It has to form from 5′ to 3′ too. It forms in pieces called the “Okazaki fragments”. First, an RNA primase lays down an RNA primer. Then, DNA polymerase III lays down a new DNA. The process repeats again and again. DNA polymerase I replaces the RNA primers with DNA. Finally, DNA ligase links the Okazaki fragments.

  71. Asma Arshad says:

    Is it an animation ……seems real!!

  72. Ha Ha says:

    Literally my biology teacher teaches things so fast and expects us to understand everything he says and take a test two days later when I basically don’t know anything. But this video is only like three minutes long and I understand everything I need to know for that test tomorrow so ummm petition to fire that biology teacher..?

  73. Arsh Ali says:

    great video!! helped a lot

    oh yeah yeah

    i dont know why im here but I must do my part

  80. Rusty says:

    No wonder kids don't like to study biology. It is presented in such a boring manner.

  81. Young Grover says:

    This is some weird looking shit

  82. ZentlysDream says:

    I felt like I could’ve had a anxiety attack

  83. LethalAmbition says:

    what kind of animation is this? This shit looked real af

  84. Pavle Lalovic says:

    I have a question, we have 23 pairs of Chromosoms, so when DNA replication begins, are they doing it all 23 in same time?If yes which chromosome contain each genes ? I think i missing something here :/.If every chromosome contains whole DNK structure why we have 23 pairs, what is diference? Are they replicating separatly one by one or in same time, and are they all together building one mayor DNK chain or separate chains?

  85. Matthew Bang says:

    how is this 720p

  86. Tjaša Starc says:

    this makes me so uncomfortable

  87. Attiya Shafique says:

    Supberb animation…love it.

  88. Sana Shariff says:

    I have watched so many videos on DNA replication, and although this video looks like its been made in the 90s it has made the most sense to me! Thank you so much Medical Institution! Godbless <3

    Beautiful. I really don't understan what is disturbing in this video?? It is just amazing animation of DNA-replication. A brief outline.
