DNA Replication Infographic with Labeled Replication Fork

Biological diagram infographic titled "DNA Replication" centered on a clean labeled pathway-style molecular diagram of a replication fork, optimized for university undergraduate learning. Show a biologically accurate DNA double helix opening into a replication bubble and one prominent replication fork, with input → output logic: parental double-stranded DNA → unwound template strands → synthesis of leading and lagging daughter strands. Mark exactly 7 labeled components around the central diagram with thin leader lines; each component must have a short English heading in quotes and a one-line English function caption in quotes. Include these 7 labels: 1) "Helicase" — "Unwinds the parental DNA duplex at the replication fork." 2) "Single-Strand Binding Proteins" — "Stabilize separated DNA strands and prevent reannealing." 3) "Topoisomerase" — "Relieves torsional stress ahead of the replication fork." 4) "Primase" — "Synthesizes short RNA primers to initiate DNA synthesis." 5) "DNA Polymerase" — "Adds nucleotides in the 5' to 3' direction using the template strand." 6) "Leading Strand" — "Synthesized continuously toward the replication fork." 7) "Lagging Strand" — "Synthesized discontinuously as Okazaki fragments away from the fork." Add small directional arrows to indicate fork movement and 5' / 3' strand polarity, with clear distinction between continuous and discontinuous synthesis. Render the DNA bases and sugar-phosphate backbone with editorial-grade scientific accuracy and clean proportions. Visual style: medical illustration, Netter-style educational plate adapted to molecular biology; monochrome scientific palette with charcoal, graphite, slate gray, and soft silver tones; calm academic mood; high contrast for sharp readable text. Use a minimal legend if needed, balanced spacing, uncluttered white or light gray background, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
