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).

What protein strands connecting the centrioles become visible during the middle prophase and are almost complete by late prophase?

spindle "a" They are called spindle fibers and are made up of microtubules. These fibers are released from the centrioles to pull apart sister chromatids during mitosis and meosisII or pull apart homologous chromosomes during meosis I.

What are strings that hold together the centrioles?

Centrioles are held together by protein filaments called microtubules. The microtubules are arranged in a specific pattern to form the cylindrical structure of centrioles. These structures play a key role in organizing the microtubule network in the cell and are involved in cell division.


What is located near the nucleus and consists of a pair of centrioles and pericentriolar material?

Centrosome - a dense network of small protein fibers near the nucleus of the cell, containing a pair of centrioles and pericentriolar material.


The process of mRNA connecting to a ribosome and reading the code to produce a protein is?

This process is called translation. During translation, the mRNA transcript is read by ribosomes, which then assemble the corresponding amino acids into a protein according to the genetic code. The ribosome moves along the mRNA, reading each codon and adding the appropriate amino acid until a complete protein is synthesized.


What are the fiber like protein units that make up the cell's cytoskeleton and the centrioles in animal cells?

microfiliments and microtubulars


How are centrioles and centrosomes related structurally?

Centrioles are barrel-shaped structures that are essential for the formation of centrosomes, cilia, and flagella. A condensed and darker area of the cytoplasm is called the centrosome When the time comes for cell division, the centrioles will appear and move to opposite ends of the nucleus. During division you will see four centrioles. One pair moves in each direction.
