怎么填变量：标题和副标题可以换成中文，如"DNA 的碱基配对 / DNA 双螺旋近景"，标注同步改成"腺嘌呤 (A)""氢键"等。换别的分子或细胞结构时（如"ATP 分子""细胞膜磷脂双分子层"），保留"背景 + 版式 + 标注数量限制"的写法，把主体细节和 7 个标注换掉。

示例图与描述一致：白底中央是绿、紫、蓝、橙四个碱基两两配对，淡蓝虚线氢键清楚，两侧是半透明蓝灰珠串骨架，右下一条橙色链标"Emerging RNA"，四周虚化的彩色分子团，7 个英文标注都拼写正确。

常见问题：

• 氢键数量画错：在提示词里保留"A–T 两条、G–C 三条"这类明确数字。
• 标注跑位：每个标注都写清"什么颜色、指向哪里"。
• 科学细节：示例的化学结构是示意图，正式教材使用前请对照课本检查环结构。

适合：生物课件、科普公众号、考研 / 高中生物笔记配图、PPT 插图。

Goal: Create a polished 3D scientific educational infographic titled {argument name="headline text" default="DNA Nucleotides"}, showing a close-up view of a DNA double helix with labeled nucleotide bases and molecular structure.

Canvas: Landscape 4:3 composition, bright white laboratory-style background with soft depth-of-field molecular clusters in pale blue, lavender, mint, and purple around the edges. Use a clean, high-resolution textbook/medical visualization style with realistic glossy translucent spheres and rods, soft shadows, and shallow depth of field.

Layout: Center the title at the top in large dark navy bold type, with the subtitle {argument name="subtitle text" default="A close-up view of the DNA double helix"} directly beneath in smaller medium-blue type. Fill the frame with a large twisting DNA double helix running from the left foreground through the center to the right side, with a second orange strand crossing diagonally through the lower right foreground. Keep the central base-pair region open and readable for labels.

Subject details: Render the DNA as a molecular ball-and-stick model combined with translucent bead-like backbone surfaces. The sugar-phosphate backbone should be two twisting chains made of semi-transparent bluish-gray spheres with orange/gold connector rods and small red atoms. In the center, show exactly 4 labeled nucleotide bases: Adenine (A) in green at upper left center, Thymine (T) in purple at upper right center, Guanine (G) in blue at lower left center, and Cytosine (C) in orange at lower right center. Adenine pairs with Thymine across the top using dotted pale blue hydrogen bonds, and Guanine pairs with Cytosine below using three dotted pale blue hydrogen-bond rows. Molecular rings should be flat aromatic ring structures with small colored atom spheres and white hydrogen atoms.

Text content and labels: Include exactly 7 callout labels with thin black pointer lines: “Adenine (A)” in green pointing to the green upper-left base; “Thymine (T)” in purple pointing to the purple upper-right base; “Guanine (G)” in blue pointing to the blue lower-left base; “Cytosine (C)” in orange pointing to the orange lower-right base; “Sugar-phosphate backbone” in black pointing to the right-side helical backbone; “Hydrogen bonds” in black pointing to the dotted bond lines between base pairs; and “Emerging RNA” in orange pointing to the orange strand crossing the lower foreground. Use crisp sans-serif typography and avoid crowding.

Visual style: Hyper-detailed scientific 3D render, glossy translucent molecular beads, realistic refraction, soft bokeh background, professional biology textbook infographic, balanced educational clarity and cinematic depth.

Constraints: Use exactly the 4 nucleotide labels and exactly the 3 structural labels listed above; do not add extra labels, icons, captions, legends, watermarks, or borders. Keep all text sharp and correctly spelled.
