DNA Replication Process dna, replication, enzine, helicase, strand, polymerase, encode, okazaki, fragments, rna, primase, primer, ligase
www.freesciencelectures.com We travel inside nucleus to see how the DNA replicates. When DNA replicates its strands are separated by enzine helicase. Single-stranded DNA binding proteines keep the strands from (...?). One DNA strand encodes the leading strand using DNA Polymerase III. Just watch to see what is going on. --- It's Never too Late to Study www.freesciencelectures.com --- Notice This video is copyright by its respectful owners.

For free download of this video please visit my webpage rufusrajadurai.wetpaint.com And other 3D animation videos visit rufusrajadurai.wetpaint.com Regards, Dr.Rufus The Lyrics of this video is here Targeting HIV replication The replication of HIV 1 is a multi-stage process. Each step is crucial to successful replication and is therefore a potential target of antiretroviral drugs. Step one is the infection of a suitable host-cell, such as a CD4-positive T-lymphocyte. Entry of HIV into the cell requires the presence of certain receptors on the cell surface, CD4 -- receptors and co-receptors such as CCR5 or CXCR4. These receptors interact with protein-complexes, which are embedded in the viral envelope. These complexes are composed of two glycoproteins: an extracellular gp 120 and a transmembrane gp 41 When HIV approaches the target cell gp120 binds to the CD4-receptors. This process is termed attachment. It promotes further binding to a co-receptor. Co-receptor binding results in a conformational change in gp120. This allows gp41 to unfold and insert its hydrophobic terminus into the cell membrane. Gp 41 then folds back on itself. This draws the virus towards the cell and facilitates the fusion of their membranes. The viral nucleocapsid enters the host cell and breaks open releasing two viral RNA-strands and 3 essential replication enzymes: Integrase, Protease and Reverse Transcriptase ...

Background Instrumentals: Back Street Boys (I Want it That Way) Lyrics: Deox / y-ribo / nuclei / ic-acid / is made from two strands, a double helix So then, the strands come apart, Nitrogen bases, they start to unzip By DNA helicase H2 bonds Between adenine and thymine H2 bonds Between cytosine and guanine H2 bonds The ladder structure is strongest in Phosphodiester links DN / A Pol-ym / er-ase Builds the new strand From the / 5" to 3" Direction H2 bonds Between adenine and thymine H2 bonds Between cytosine and guanine H2 bonds The ladder structure is strongest in Phosphodiester links Now I can see that its replicating In a way thats quite interesting (YEAH!) No matter the distance, the leading strand Is followed by the lagging one Finally...the ligase Seals up all the breaks A new....a new....a new....DNNNNNNNNNNA! And it starts again!! Oh, how I love bi-olo-gy (yeah yeah yeah) It's better than chemistry And next time I have to go pee (I know) what's happening inside of me

DNA replication is the process of copying a double-stranded DNA molecule to form two double-stranded molecules.[1][2] The process of DNA replication is a fundamental process used by all living organisms as it is the basis for biological inheritance. As each DNA strand holds the same genetic information, both strands can serve as templates for the reproduction of the complementary strand. The template strand is preserved in its entirety and the new strand is assembled from nucleotides. This process is called "semiconservative replication". The resulting double-stranded DNA molecules are identical; proofreading and error-checking mechanisms exist to ensure near perfect fidelity. ¤ In a cell, DNA replication must happen before cell division can occur. DNA synthesis begins at specific locations in the genome, called "origins", where the two strands of DNA are separated.[3] RNA primers attach to single stranded DNA and the enzyme DNA polymerase extends the primers to form new strands of DNA, adding nucleotides matched to the template strand. The unwinding of DNA and synthesis of new strands forms a replication fork. In addition to DNA polymerase, a number of other proteins are associated with the fork and assist in the initiation and continuation of DNA synthesis. DNA replication can also be performed artificially, using the same enzymes used within the cell. DNA polymerases and artificial DNA primers are used to initiate DNA synthesis at known sequences in a template molecule ...

www.freesciencelectures.com First the DNA Wrapping is animated. The wrapping allows 6 feet of the long DNA molecule to be densely packed into the tiny nucleus of every cell. The process starts when DNA is wrapped around special protein molecules called histones. The combined loop of DNA and protein is called a nuclei zone. Next the nuclei zones are packed into a thread. The end result is fiber known as chromatin. This fiber is looped and coiled yet again leading 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. Using computer animation based on molecular research we are now able to see how DNA is actually copied in living cells. An assembly line of amazing biochemical machines are pulling apart the DNA double helix and cranking out a copy of each strand.
