The cytoskeleton is the three-dimensional scaffolding present in eukaryotic cells. The structure functions similarly to both the muscles and skeleton of animals in that it provides support and causes movement. Its struct... More » Science Biology Cells

A replicated chromosome of a eukaryotic cell consists of two identical sister chromatids joined by a centromere. Each chromatid is a long, thin chromatin fiber containing one DNA molecule, DNA-bound proteins and RNA. The... More »

Kinetochores are the protein structures where spindle fibers attach on chromatids; this happens during cell division and is used to pull sister chromatids apart. Kinetochores start — and are in charge of — the movements ... More »

Eukaryotic cells are advanced cells that have, at minimum, a cellular membrane surrounding cytoplasm, a cytoskeleton and membrane-covered organelles. More advanced eukaryotic cells also contain a nucleus that protects ge... More » Science Biology Cells

The cytoskeleton moves organelles around in a cell, gives the cell shape, helps the cell to move and aids the cell during cell division. The cytoskeleton is made up of protein fibers. More »

The role of a cytoskeleton in a living cell is to supply structure to the cell, give the cell the ability to move and ensure proper cell division during cellular reproduction. The cytoskeleton contains three types of fil... More »

According to science writer Clare Smith for SeattlePi, the cell membrane is kept from collapsing by its phospholipid bilayer, maintenance of the correct temperature, a cytoskeleton and cell junctions. These are necessary... More »
