Ribosome mRNA Translation

A minimalist 3D scientific illustration of translation at a ribosome, rendered with soft ambient lighting on a white background. The ribosome is shown as two subunits (large 60S subunit — warm ochre blob, small 40S subunit — cooler tan shape) clamped around a horizontal mRNA strand (pale grey ribbon with codon triplets marked as alternating dark-grey and light-grey nucleotide blocks). Three tRNA molecules occupy the A, E, and P sites: each is shown as an L-shaped clover-leaf schematic in coral, mint, and lavender respectively, with a single amino acid circle hanging from the anticodon loop. A growing polypeptide chain (linked coloured spheres) exits through the exit tunnel on the left. Labels in thin 8 pt sans-serif: "A site", "P site", "E site", "mRNA", "Polypeptide". Subtle depth-of-field blur on background elements.

一幅极简风格的核糖体翻译过程 3D 科学插图，柔和环境光，白色背景。核糖体由大亚基（暖赭色）和小亚基（冷棕褐色）夹住横向 mRNA（浅灰色带，深浅灰交替标注密码子三联体）。A、P、E 位分别有一个 tRNA（珊瑚色、薄荷色、薰衣草色 L 形三叶草图形），各自的反密码子环下方悬挂一个氨基酸小球。生长中的多肽链（彩色小球串）从左侧出口隧道延伸而出。8 pt 无衬线细体标签标注各位点与结构。
