A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

A complete, student-led lesson on cell structure, cell division, and cancer growth. Students work their way through illustrations and animated tutorials, and answer review questions along the way. There is a self-checking quiz at the end...

[Free Registration/Login may be required to access all resource tools.] Cell division is just one of several stages that a cell goes through during its lifetime. Students will learn about the phases of the cell cycle, specifically the...

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

[Free Registration/Login may be required to access all resource tools.] No matter what the cell, all cells come from preexisting cells through the process of cell division. This module provides an overview of cell division in prokaryotes...

[Free Registration/Login may be required to access all resource tools.] Cells do eventually wear out. At that point, they need to be replaced. This is one reason that your cells divide. New cells that result after cells divide are also...

[Free Registration/Login may be required to access all resource tools.] An overview of cell division in prokaryotes and eukaryotes.

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information. Links to a video and a test are provided.

[Free Registration/Login may be required to access all resource tools.] A description of the stages of eukaryotic cell division, a summarization of mitosis and the metaphase plate, an explanation of the function of the centrioles and the...

This multimedia article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on buttons along the bottom of the page. The topic is the study of cell division, mitosis, and cell...

Chromosomes are made from DNA. Genes are short sections of DNA. Genetically identical cells are produced by a type of cell division called mitosis. In sexual reproduction, a male gamete fuses with a female gamete to produce a new cell....

In this third unit of a Biology course, students learn about cells and cell structure. They compare prokaryotic and eukaryotic cells and learn about the specialized structures in a cell and what their functions are. They will also learn...

Overview of mitosis and the cell structures that are critical to the process.

[Free Registration/Login may be required to access all resource tools.] During mitosis, the DNA in a nucleus must replicate. The copied DNA is divided into two genetically identical sets, so that after cytokinesis or cell division, each...

[Free Registration/Login may be required to access all resource tools.] The process of cell division in eukaryotic cells is carefully controlled. The cell cycle is the life cycle of a cell, with cell division at the end of the cycle....

This lesson focuses on cell specialization. This cell must divide to produce a multi-cellular organism. It must also differentiate, so that its cells develop features that enable them to fulfil specific roles. Links are provided to a...

[Free Registration/Login may be required to access all resource tools.] DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. DNA replication occurs during the S...

[Free Registration/Login may be required to access all resource tools.] How do you make a cell with half the DNA? Meiosis. This activity outlines the phases of meiosis, provides an overview of sexual reproduction, and describe how...
