According to cell theory, where do cells come from?
Previously existing cells

Identify this stage of the cell cycle.
Interphase (a single nucleus is present)
100
Name the cell structure that joins two sister chromatids of a chromosome together.
Centromere
100
Name a disorder in the body where some cells no longer have scheckpoints that control growth and reporduction.
Cancer

What is the cell cycle? As a whole, what does it explain?
The cell cycle is the life cycle of a cell. It explains how cells make more cells.
200
What are the four phases of mitosis?
Prophase
Metaphase
Anaphase
Telophase

Fill in the blank:
The "rope" that is attached to the centromere of a chromosome is called the __________.
The "anchors" that move to opposite ends of the cell are called the __________.
Spindle Fiber
Centrioles
200
Paired chromosomes are called...?
Homologs or homologous chromosomes.

What is the cell cycle used for in single-celled organisms?
Asexual Reproduction
300
Explain what happens in a cell during anaphase.
Sister chromatids are being separated.
300
Name a cell structure besides DNA that is present through the entire cell cycle.
Plasma Membrane
Centrioles
300
Which is similar to mitosis, meiosis I or meiosis II?
Meiosis II

Why is it important that DNA is duplicated during interphase of the cell cycle?
The cell needs to create two copies of DNA to create two new cells.
400
Draw the different stages of mitosis.

The DNA of a cell changes into different forms throughout the cell cycle. Name these forms of DNA in an order that reflects the cell cycle.
Chromatin turns into chromosomes in prophase. chromosomes turn into sister chromatids in anaphase. Sister chromatids turn back into chromatin during telophase.
400
Protein synthesis is occuring in a ribosome. Is this a part of transcripiton or translation?
Translation

Explain how multicellular living things use the cell cycle to grow and heal itself.
Multicellular living things use the cell cycle to grow by creating more cells to add to their body. They use the cell cycle to heal by creating replacement cells for any damaged cells.

Create a detailed diagram of the entire cell cycle. Identify the three main parts of the cell cycle and list what happens in each of these stages.

1. Centriole
2. Chromosomes
3. Spindle Fiber

Can a virus reproduce all on its own?
No, viruses are not alive and cannot reproduce on their own.
