Understand process of constructing an mRNA molecule from DNA is known as transcription.
CK-12 Foundation
Ck 12: Life Science: Passive Transport
[Free Registration/Login may be required to access all resource tools.] The cell membrane is semi-permeable. Sometimes molecules need the help of special transport proteins or an input of energy to help them move across it. When an input...

Ck 12: Life Science: Dna Structure and Replication
[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...
CK-12 Foundation
Ck 12: Biology: First Organic Molecules
[Free Registration/Login may be required to access all resource tools.] Examines how the first organic molecules were formed.
TeachEngineering
Teach Engineering: Surfactants: Helping Molecules Get Along
Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding...

[Free Registration/Login may be required to access all resource tools.] Covers the structure and properties of water.
CK-12 Foundation
Ck 12: Life Science: Diffusion
[Free Registration/Login may be required to access all resource tools.] The process of molecules moving from an area where there are lots of molecules to an area where there are fewer molecules is known as diffusion. The diffusion of...
CK-12 Foundation
Ck 12: Life Science: Enzymes in the Digestive System
[Free Registration/Login may be required to access all resource tools.] Chemical digestion could not take place without the help of digestive enzymes. An enzyme is a protein that speeds up chemical reactions in the body. Digestive...
CK-12 Foundation
Ck 12: Life Science: Carbon Cycle
[Free Registration/Login may be required to access all resource tools.] Carbon is one of the most common elements found in living organisms. Chains of carbon molecules form the backbones of many molecules, such as carbohydrates,...
CK-12 Foundation
Ck 12: Life Science: Types of Nutrients
[Free Registration/Login may be required to access all resource tools.] Carbohydrates, proteins, and lipids contain energy. When your body digests food, it breaks down the molecules of these nutrients. This releases the energy so your...
CK-12 Foundation
Ck 12: Life Science: Transcription of Dna to Rna
[Free Registration/Login may be required to access all resource tools.] DNA is located in the nucleus. Proteins are made on ribosomes in the cytoplasm. Remember that information in a gene is converted into mRNA, which carries the...
