What is the small protein structure critical to cell division?
ribosomes ?
Each individual protein structure that helps to move the chromosomes apart during mitosis is called what?
Name of protein is tubulin which is called spindle fibers when moving chromosomes .
What does not occur during interphase excretion of wastes cell repair protein synthesis nuclear division?
you probably asked this a long time ago but the answer is nuclear division, because interphase is befor cell division. :)
How are the nuclear envelope nucleolus and chromosomes relatedto one another briefly descriebe each of these structures?
The nucleus consists of two membranes, one called the NUCLEAR ENVELOPE. The nuclear envelope surrounds the cell's genetic information. This genetic information is contained in structures called CHROMOSOMES. In addition to chromosomes, most nuclei contain a region called the NUCLEOLUS.
When chromosomes are visible?
Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.
Which structure contains DNA and protein?
B chromosomes
What chromosomes can be describe as?
Chromosomes are an organized structure of DNA and protein that is found in cells.
Helps maintain the structure of chromosomes and control the activity of genes?
protein
What organism structure that organizes motion of chromosomes?
Vesicle

What do spindle finbers do during mitosis?
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores. Kinetochores are protein formations that develop on each chromosome around the centromere, which is a region located near the middle of a chromosome. Other microtubules bind to the chromosome arms or extend to the opposite end of the cell. During the cell division phase called metaphase, the microtubules pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane. The cell goes through an important checkpoint to ensure that all of the chromosomes are attached to the spindle and ready to be divided before it proceeds with division. Next, during anaphase, the chromosomes are simultaneously separated and pulled by the spindle to opposite poles of the cell.
What are rod-shape structures found in a nucleus?
Chromosomes are the rod-shaped specimens found in the nucleus. They are the hereditary material called DNA. They form when a single DNA molecule and its associated proteins coil tightly before cell division.
What are the network of nuclear threads composed of DNA and protein that condense to form chromosomes during mitosis is called?
Chromatin
