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...

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 ♥️ .

@explained_science
The process of making a protein from DNA is called gene expression. It happens in two main steps: 1. Transcription – The DNA sequence of a gene is copied into mRNA inside the nucleus. 2. Translation – The mRNA travels to the ribosome, where its code is read and assembled into a chain of amino acids, forming a protein. This flow of information is often called the central dogma of molecular biology. • Follow - @science__explanation • #instagram #study #studygram #education #student #studying #school #learning #studynotes #learn #science #knowledge

Daily A Level Biology exam question (AQA) 📈 Describe the process of semi-conservative DNA replication (5) 1. DNA helicase breaks hydrogen bonds between complementary bases, unwinding the double helix 2. Both strands act as templates 3. Free DNA nucleotides attracted to exposed bases and join by specific complementary base pairing 4. Hydrogen bonds form between adenine-thymine and guanine-cytosine 5. DNA polymerase joins adjacent nucleotides on new strand by condensation reactions 6. Forming phosphodiester bonds Semi-conservative - each new DNA molecule consists of one original / template strand and one new strand #alevelbiology #biologyalevel #biologyclass #biology #biologystudent

Respuesta al Daño del ADN Cuando en la célula hay daño al #ADN, la primera opción es la reparación, así que se activan las vías que remueven el daño de manera específica, este mecanismo se conoce como respuesta de daño al ADN (DNA damage response: DDR). Vías de reparación del ADN: a.- Reparación por excisión de bases (BER: base excision repair). Se activa para la reparación de rompimientos de cadena sencilla. b.- Reparación por excisión de nucleótidos (NER: nucleotid excision repair). Se activa para la reparación de rompimientos de cadena sencilla. c.- Reparación de discordancias (MMR: mismatch repair). Se activa para la reparación de rompimientos de cadena sencilla. d.- Recombinación homóloga (HR: homologous recombination). Se activa para la reparación de rompimientos de cadena doble. e.- Unión de extremos no homólogos (NHEJ: non-homologous end joining). Se activa para la reparación de rompimientos de cadena doble. f.-Reparación de entrecruzamientos (ICL: interstrand cosslink repair). El éxito de la reparación depende de varios factores, entre ellos: cuánto daño ha sufrido el ADN y qué tipo de daño es. De acuerdo con eso, la célula tiene opción de reparar el daño con diferentes grados de fidelidad, pero también puede suceder que el tipo de daño sea imposible de reparar y que se manifieste en forma de aberraciones cromosómicas, las cuales se pueden manifestar en forma de remanencias nucleares conocidas como micronúcleos (MN). biology #biologia #study #science #animation #med #dna Fuente: Reposted from @biologicallscience; Rojas et al .
