细胞骨架大部分由微丝组成，微丝主要由可收缩的肌动蛋白组成。
A large portion of the cytoskeleton consists of threadlike microfilaments composed mainly of the contractile actin.
微丝骨架是细胞骨架的重要组成部分，它由肌动蛋白和肌动蛋白结合蛋白组成，广泛存在于真核细胞中。
As the important part of cytoskeleton, microfilament skeleton is composed of actin and actin-binding proteins, and widely exists in eukaryotic cells.
绿色为微丝，红色为肌动蛋白，蓝色为染色质，中心点复制成两个。
Microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue.
肌动蛋白呈丝状，分布于细胞质外围靠近细胞膜处，沿细胞轮廓排列走行，而在核周则无微丝分布；
Filamentous actin was distributed in the cytoplasm near the cell periphery Department, arranged to go along the cell contour lines, while no actin distribution in the nucleus;
