What else can I help you with?
What are the jobs of protein fibers during mitosis-?
During mitosis, protein fibers attach to the chromosomes on opposite ends of the cell, then help to pull them apart so that the cell can divide into daughter cells with copies of all the chromosomes.
Why do individual chromosomes more difficult to see during interphase than during mitosis?
During mitosis the fibers of each individual chromosome are drawn together, forming the tightly packed chromosomes that you can see through a microscope. If you are doing a worksheet for biology go to this website [http://www.docstoc.com/docs/11904856/BioReplication-Quiz-Review-Answer-Key/] it has all the answers except for 9,10,and 11
What structure is produced when protein fibers radiate from from centrioles?
Cell PlateCell Plate
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
What specifically separates during mitosis?
A cell splits in two, with each half getting half of the chromosomes.
What protein structure moves chromosomes?
The motor protein structure that moves chromosomes during cell division is called the kinetochore. It forms on the centromere of the chromosome and interacts with microtubules to facilitate chromosome movement. The coordinated activity of kinetochores in the cell ensures accurate segregation of chromosomes during mitosis.
Where do microtubules attach to chromosomes during mitosis?
Microtubules attach to chromosomes at the kinetochore, a protein structure located at the centromere region of each chromosome. This attachment ensures accurate segregation of chromosomes during mitosis.
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.
What are the jobs of protein fibers during mitosis-?
During mitosis, protein fibers attach to the chromosomes on opposite ends of the cell, then help to pull them apart so that the cell can divide into daughter cells with copies of all the chromosomes.
What role do spindles play in mitosis?
Spindles are protein structures that help separate chromosomes during mitosis. They attach to chromosomes and help move them to opposite sides of the dividing cell, ensuring that each daughter cell receives the correct number of chromosomes.
Shortening and fattening of the chromosomes at the start of mitosis?
At the start of mitosis, chromosomes condense or shorten by coiling more tightly. This condensation allows easier segregation and movement of chromosomes during cell division. Additionally, the chromosomes appear fatter due to increased DNA and protein compaction.
When do spindle fibers attach to chromosomes?
Spindle fibers attach to chromosomes during metaphase of mitosis. Special protein structures called kinetochores on the chromosomes interact with the spindle fibers to ensure proper alignment and segregation of the chromosomes during cell division.

What are the network of nuclear threads composed of DNA and protein that condense to form chromosomes during mitosis is called?
The network of nuclear threads composed of DNA and protein that condense to form chromosomes during mitosis is called chromatin. Chromatin consists of DNA wrapped around histone proteins, and it undergoes further condensation to form visible chromosomes during cell division.

The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
