How do copies of DNA condense into chromosomes that separate during cell division?
During cell division, copies of DNA condense into chromosomes through a process called condensation. This condensation helps to organize and package the DNA into a more compact structure, allowing it to be easily separated and distributed to daughter cells. The chromosomes then align along the center of the cell and are pulled apart by the cell's machinery, ensuring that each daughter cell receives a complete set of chromosomes.

The name for the process of cell division that produces copies of cells with the 46 chromosomes is?
The process of cell division that produces copies of cells with 46 chromosomes is called mitosis. In mitosis, a parent cell divides to produce two identical daughter cells, each containing the same number of chromosomes as the parent cell.
Summarize the events that occur during mitosis and cytokinesis?
During mitosis, the cell's nucleus divides into two daughter nuclei with identical DNA copies. This process involves stages such as prophase, metaphase, anaphase, and telophase. Cytokinesis follows mitosis and involves the division of the cell's cytoplasm to create two separate daughter cells.
Do chromosomes make copies of themselves?
Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
What is the relationship between chromosomes and chromatids?
Chromosomes are the condensed and replicated form of DNA. The two identical halves of the chromosomes are known as sister chromatids. Before division, while the chromatids are still attached, they form one chromosome. However, when anaphase (i.e the stage when chromosomes split) starts and they are separated, the two chromatids on the opposite poles of the cell become complete chromosomes.
What do chromosomes do before mitosis?
Before mitosis, chromosomes replicate to form identical sister chromatids. This ensures that each daughter cell receives a complete set of genetic information during cell division. Additionally, chromosomes condense to make sure they are organized and can be properly distributed to each daughter cell.
What happens to DNA and chromosomes when cells in most parts of the body divide?
During cell division, DNA replicates to form two identical copies that are then separated into two new cells. Chromosomes condense, align at the center of the cell, and are pulled to opposite ends during cell division. This ensures that each new cell receives a complete set of chromosomes with the same genetic information.

What is the relationship between chromaids and chromosomes?
Chromatids are two identical copies of a chromosome that are joined together at the centromere. Chromosomes are made up of two chromatids and are only seen during cell division. Chromatids separate during cell division to form individual chromosomes that are distributed to daughter cells.

Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
What are double-stranded chromosomes known as?
Double-stranded chromosomes are known as sister chromatids. They are exact copies of each other, formed during DNA replication and are held together by a specialized region called the centromere. Sister chromatids separate during cell division.
What is the relationship between chromosomes and chromatids?
Chromosomes are the condensed and replicated form of DNA. The two identical halves of the chromosomes are known as sister chromatids. Before division, while the chromatids are still attached, they form one chromosome. However, when anaphase (i.e the stage when chromosomes split) starts and they are separated, the two chromatids on the opposite poles of the cell become complete chromosomes.
Chromosomes are called what once they have duplicated in preparation for division?
During prophase, the chromosomes in a cell's nucleus condense to the point that they can be viewed using a light microscope. ... Because each chromosome was duplicated during S phase, it now consists of two identical copies called sister chromatids that are attached at a common center point called the centrome or chromosomal duplications
What do chromosomes do before mitosis?
Before mitosis, chromosomes replicate to form identical sister chromatids. This ensures that each daughter cell receives a complete set of genetic information during cell division. Additionally, chromosomes condense to make sure they are organized and can be properly distributed to each daughter cell.
Why are chromosomes copied during cell division?
Chromosomes are copied during cell division to ensure that each new cell receives a complete set of genetic information. This process helps maintain the proper number of chromosomes in daughter cells and allows genetic information to be passed on accurately during cell division.
What is the genetic material contained in each of the 46 chromosomes of a human cell just before division?
The genetic material in each of the 46 chromosomes of a human cell just before division is DNA. DNA carries the instructions for building and maintaining an organism. During cell division, the DNA is replicated and then divided equally between the new cells.
How do chromosomes replicate during mitosis?
During mitosis, chromosomes replicate by first unwinding and duplicating their DNA. Each chromosome then forms a sister chromatid, creating two identical copies. These sister chromatids are held together at a region called the centromere. Finally, during cell division, the sister chromatids separate and move to opposite ends of the cell, ensuring that each new cell receives a complete set of chromosomes.
