The cell fiber made of twisted strands of protein is called collagen. Collagen is a key structural protein found in various connective tissues, including skin, tendons, and ligaments. It provides strength and elasticity, contributing to the overall integrity and resilience of these tissues.

The twisted ladder shape of DNA, known as the double helix, provides stability and protection for genetic information. The structure allows for efficient packing of genetic material within the cell nucleus while still being easily accessible for processes like replication and transcription. The two strands of DNA can also separate for replication and protein synthesis.
During the M phase of cell division, particularly in mitosis, the radiating protein strands at the poles of an animal cell are primarily composed of microtubules. These structures form the mitotic spindle, which helps to segregate chromosomes into the daughter cells. The microtubules extend from the centrosomes, anchoring to the kinetochores of chromosomes to ensure proper alignment and separation. This organization is crucial for accurate cell division and genetic stability.

They use the ribosomes to connect strands from your DNA
During Metaphase the protein strands that attach to the centromere region are called spindle fibres.
Fibroblast
The network of long protein strands in the cytosol that helps maintain the shape and size of a eukaryotic cell is the cytoskeleton. It is made up of three main types of filaments: microtubules, actin filaments (microfilaments), and intermediate filaments. These filaments provide structural support, help with cell motility, and are involved in various cellular processes such as cell division and intracellular trafficking.

DNA consists of two strands that are twisted together in a double helix structure. These strands contain genetic information in the form of genes, which determine an organism's traits and characteristics. The pairing of the strands allows for the accurate replication and transmission of genetic information during cell division and reproduction.

These strands are called spindle fibers. Each replicating chromosome lines up vertically on a spindle fiber during metaphase. During anaphase, the fibers pull the replicating chromosomes apart (leaving one chromosome to go to either end of the cell).
The meshlike network of protein fibers that supports the shape of the cell is either cellulose (cell wall) or the cytoskeleton (inside).
microfiliments and microtubulars
The rough endoplasmic reticulum (RER) is where ribosomes will congregate to attach onto mRNA strands and transcribe the mRNA into protein strands. The smooth endoplasmic reticulum (SER) is where the protein strands made in the RER are folded, checked for problems and labeled for delivery to the appropriate location (cell membrane, other organelles, to be stored in a lysosome, etc.).
