if a cell has 64 chromosomes together, all the offspring cells will have 64 chromosomes each.


Which structure connects the replicated chromosomes?

The centromere is the structure that connects the replicated chromosomes during cell division. It plays a crucial role in ensuring that each daughter cell receives the correct number of chromosomes.


The cell organelles that assist with cell division are the?

The cell organelles that assist with cell division are the centrioles. Centrioles play a crucial role in organizing the microtubules involved in cell division, helping to ensure the accurate separation of chromosomes during mitosis.


Are chromosomes a part of the plant cell?

Yes, chromosomes are part of plant cells. They are located in the nucleus of the plant cell and carry genetic information in the form of DNA. Chromosomes play a crucial role in cell division and inheritance of traits in plant cells.


What does the centrioles do?

Centrioles are cylindrical structures that play a key role in cell division by organizing the microtubules that form the spindle apparatus. The spindle apparatus helps to separate chromosomes during cell division, ensuring that each daughter cell receives the correct number of chromosomes.


What is the relationship between microtubules and spindle fibers in cell division?

Microtubules are the building blocks of spindle fibers, which are essential for cell division. During cell division, microtubules form the spindle fibers that help separate chromosomes and ensure each new cell receives the correct number of chromosomes. In summary, microtubules are the structural components of spindle fibers that play a crucial role in the process of cell division.


What plays a role in cell division?

Nuclear division plays a role in cell division.


What is the term for when chromosomes fail to separate during cell division?

The term for when chromosomes fail to separate during cell division is called nondisjunction.


What does meiosis cause the chromosomes to do during cell division?

Meiosis causes the chromosomes to separate and reduce their number in half during cell division.


What is a centrosome and what is its role in cell division and organization?

A centrosome is a small organelle found in animal cells that plays a key role in cell division and organization. It is responsible for organizing the microtubules that help separate chromosomes during cell division. Additionally, the centrosome helps maintain the cell's shape and structure by serving as a center for the organization of the cell's cytoskeleton.


How many chromosomes does a human cell have before division?

64 chromosomes


When does the number of chromosomes in a cell halve?

In cell division and reproduction.
