DNA replication is a vital, semi-conservative process where each new DNA molecule retains one parental strand and one newly synthesized strand, as proven by the Meselson-Stahl experiment. Replication starts at origins of replication—single in prokaryotes (e.g., OriC in E. coli) and multiple in eukaryotes. Helicase unwinds the DNA, while single-strand binding proteins prevent reannealing. Primase lays down an RNA primer, allowing DNA polymerase to extend new DNA strands in the 5’→3’ direction. The leading strand is synthesized continuously, while the lagging strand forms Okazaki fragments, later joined by DNA ligase after primer removal. Topoisomerases relieve supercoiling, and proofreading ensures replication accuracy. Animation credit 📸- Thanks to "Your genome " Official Youtube Channel ♥️ .

DNA helicase and polymerase work cooperatively at the replication fork to perform leading-strand DNA synthesis. First, an enzyme called a DNA helicase separates the two strands of the DNA double helix. This forms a structure called a replication fork that has two exposed single strands. Other enzymes called DNA polymerases then use each strand as a template to build a new matching DNA strand. . . .

One of the most fascinating process in biology. DNA replication is the biological process by which a cell makes an exact copy of its DNA before cell division. It's essential for growth, repair, and reproduction in all living organisms. Key Steps in DNA Replication 1. Initiation - Begins at specific sites called origins of replication. - Helicase enzyme unwinds the double helix, forming a replication bubble with two replication forks. - Single-strand binding proteins (SSBs) stabilize the unwound strands. 2. Primer Synthesis - Primase lays down short RNA primers on each strand to provide a starting point for DNA synthesis. 3. Elongation - DNA polymerase III adds new nucleotides. - One strand (the leading strand) is synthesized continuously. - The other (the lagging strand) is synthesized in short fragments called Okazaki fragments, which are later joined by DNA ligase. 4. Termination - Once the entire DNA molecule is copied, enzymes remove the RNA primers and replace them with DNA. - DNA ligase seals any gaps, completing the replication process. 📹 by yourgenome (yt) #molecularbiology #molecularmedicine #cellmolecularbiology #microbiology Direction of replication is...

A helicase de DNA é uma enzima que desenrola a hélice de DNA de dupla fita durante os processos de replicação, transcrição e reparo do DNA. Ela utiliza energia da hidrólise de ATP para quebrar as ligações de hidrogênio entre os pares de bases complementares, permitindo que as fitas de DNA se separem e possibilitando que outras enzimas acessem o DNA para diversos processos celulares.

DNA replication is the process by which a cell makes an exact copy of its DNA. It occurs in several steps: Initiation: The enzyme helicase unwinds the DNA at the origins of replication, creating two single strands. Primer Binding: Primase synthesizes short RNA primers to provide a starting point for DNA synthesis. Elongation: DNA polymerase adds nucleotides to the primer, forming the new DNA strands. The leading strand is made continuously, while the lagging strand is synthesized in short segments (Okazaki fragments). Proofreading: DNA polymerase checks for errors, correcting mistakes during replication. This ensures the accurate copying of genetic material for cell division.
