DNA Replication Made Easy

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. This process occurs in all living organisms and is the basis for biological inheritance. The cell possesses the distinctive property of division, which makes replication of DNA essential.

DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.

In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.

DNA replication, like all biological polymerization processes, proceeds in three enzymatically catalyzed and coordinated steps: initiation, elongation and termination.

Replication fork

Many enzymes are involved in the DNA replication fork.
The replication fork is a structure that forms within the nucleus during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together. The resulting structure has two branching "prongs", each one made up of a single strand of DNA. These two strands serve as the template for the leading and lagging strands, which will be created as DNA polymerase matches complementary nucleotides to the templates; the templates may be properly referred to as the leading strand template and the lagging strand template.

Stumbled upon Hidden DNA Potentional on shirlest and it opened up a whole new world for me. The ideas presented are revolutionary, and I’ve seen major changes in my life since then.

Bless you, none of my reading would tell me what "5 prime" or "3 prime" meant and this is so so helpful! Your drawings are so satisfying to watch, and so clear. Thank you!

Thanks for explaining about the 3‘ to 5‘ concept in detail, I haven’t seen that in other videos and it helps me to relate this to other concepts.

many you tube videos exist, but all confuse us more than elucidating. Thank you for clarity. May be we should also get some still pictures as the video goes on to refer to them in piece meal

thanks a lot !!! I just finished my STPM biology paper and one of the essay question is about dna replication. Thanks for easier explanation about this topic which lets me more unstanding about the process of dna replication😆
