Infographie 3D des Nucléotides de l'ADN

A polished 3D scientific educational infographic in a landscape 4:3 composition titled "[DNA Nucleotides]" centered at the top in large dark navy bold typography, with the subtitle "[A close-up view of the DNA double helix]" directly beneath in smaller medium-blue type. Setting & Background: Bright white laboratory-style backdrop with soft depth-of-field molecular clusters in pale blue, lavender, mint, and purple around the margins. Clean, high-resolution scientific visualization with glossy translucent surfaces and soft shadows. Subject & Composition: A large twisting DNA double helix spans diagonally from the left foreground through the center toward the right, with a secondary orange single strand crossing diagonally through the lower right foreground. The central base-pair area is open and clearly readable. The DNA is rendered as a hybrid ball-and-stick and translucent bead-like model. The sugar-phosphate backbone consists of two twisting chains of semi-transparent bluish-gray spheres connected by orange/gold rods with small red atoms. Base Pairs & Molecular Details: Exactly 4 labeled nucleotide bases in the center: - Adenine (A): flat green aromatic ring at upper left center. - Thymine (T): flat purple aromatic ring at upper right center, paired with Adenine via two dotted pale blue hydrogen bonds. - Guanine (G): flat blue aromatic ring at lower left center. - Cytosine (C): flat orange aromatic ring at lower right center, paired with Guanine via three dotted pale blue hydrogen bond rows. Labels & Typography: Exactly 7 callout labels connected by crisp, thin black pointer lines in clear sans-serif text: - "Adenine (A)" in green text pointing to the green base. - "Thymine (T)" in purple text pointing to the purple base. - "Guanine (G)" in blue text pointing to the blue base. - "Cytosine (C)" in orange text pointing to the orange base. - "Sugar-phosphate backbone" in black text pointing to the helical backbone. - "Hydrogen bonds" in black text pointing to the dotted bonds. - "Emerging RNA" in orange text pointing to the orange strand in the foreground. Style: Hyper-detailed medical textbook 3D render, realistic glossy refraction, shallow depth of field, balanced pedagogical clarity.
