Prophase
What is prophase?
It's the process that separates the duplicated genetic material carried in the nucleus of the nucleus of a parent cell into two identical daughter cells.
What is the definition of Metaphase?
When the chromosomes become attached to the spindle.
What is the definition of Anaphase?
It's the stage in meiotic or mitotic cell division where the chromosomes move away from one another to opposite poles and spindles.
What is the definition of Telophase?
When the chromatids or chromosomes move to opposite ends of cells and two nuclei are formed.
What are chromosomes?
It's a threadlike structure of nucleic acids and protein that is found in the nucleus of most living cells that is carrying genetic information in the form of genes.
What can you see under a microscope prophase?
You can see the DNA tightly wounding.
Is Metaphase first or second in Mitosis?
Second
Is Anaphase before or after Telophase?
Its after
Is Telophase last or first?
Last
What is cytokinesis, and when does it occur?
When the physical process of cell division in which it divides the cytoplasm of a parental cell into two daughter cells.
What is a chromatin?
It’s unwound DNA that condenses forming chromosomes.
What are spindle fibers?
Its protein structures that pull apart genetic material in a cell when the cell divides.
What are sister chromatids?
They are identical copies of the same chromosomes that are formed by DNA replication.
What is a nuclear?
Its energy in a nucleus or core of an atom. Nuclear energy can be used to create electricity.
Definition of nucleus?
It's the central and most important part of an object, part of an object movement or group, forming the basis for its activity and growth.
What is the name of the membrane around the nucleus that disappears?
Nuclear envelope.
What do Chromosomes do?
They line up in the center/equator of the cell.
How do two sets of chromosomes occur?
When the two sister chromatids of each chromosome separate as the spindles pull the chromatids apart.
What happens after the spindle dissolves?
Nuclear envelopes form around the chromosomes in both cells.
What are sister chromatids?
They are two identical copies of the same chromosomes formed by DNA replication.
What other event happens near the end of Prophase?
The spindles form and attach to the chromosomes that help them move.
What's going on in the image?
The chromosomes line up in a row , each on top of the next.
What's going on in the image?
The chromosomes are separating as the spindles are pulling the chromatids apart.
What's happening in the image?
The spindle is dissolving and the nuclear envelopes form around the chromosomes in both cells.
How many pairs does a chromosome divide into?
In human cells, our DNA is divided up into 23 pairs of chromosomes.
