Online Class: Biology 101 - Explore the Mystery of Life
Biology, the science of life, concentrates on the structure, function, distribution, adaptation, interactions, origins and evolution of living organisms, a grouping which encapsulates both plants and animals. Biology Basics will encompass the principles of biology that include the structure and function of the cell to the complexities of current Ecological issues. Topics will include: Chemistry Fundamentals, Cell Biology, Classic and Molecular Genetics, Origin and Principles of Evolution, Plant form and function, animal form and function, and Ecology.

Online Class: Microbiology 101
Regardless of whether you are a serious student considering a career in microbiology or a layperson who just wants to learn everything you can about the world around you, Microbiology 101 is guaranteed to change the way you look at the world.

Online Class: Cell and Molecular Biology 101
This course will provide a full overview of the world of cell and microbiology. We will first provide the basic components comprised within all living things before moving onto to how organisms' internal systems work and how they coexist and contend with external elements.

Chemical Bonds

Because of the tendency of atoms to complete their outer energy shells with the stable number of electrons for each shell, atoms with incomplete shells have a tendency to gain electrons, lose electrons or share electrons. Atoms that have gained or lost electrons become ions. Oppositely charged ions form ionic bonds. Atoms that share electrons form covalent bonds. A much weaker, but very important bond in biological systems is the hydrogen bond.

 

 

Plant, Animal and Bacteria Cell Models

Living cells are divided into two types - procaryotic and eucaryotic (sometimes spelled prokaryotic and eukaryotic). This division is based on internal complexity. The following pages can provide graphic roadmaps to the organization of both of these cell types.
 

The Periodic Table

You've probably seen this table before — it kind of looks like a mess of random letters and numbers, right? Well it's actually one of the most important tools for understanding chemistry!

 

Mitosis / Meiosis

All new cells come from previously existing cells. New cells are formed by the process of cell division which involves replication of DNA and division of the cell’s nucleus (karyokinesis) and division of the cytoplasm (cytokinesis). There are two types of nuclear division: mitosis and meiosis.
 

RNA (ribonucleic acid)

A class of nucleic acids characterized by the presence of the sugar ribose and the organic base uracil. By contrast, DNA contains deoxyribose and thymine, respectively. Most RNA molecules, including messenger RNA and transfer RNA, act as cellular intermediaries; that is, they convert the genetic information stored in DNA into the proteins that provide cells with structure and enable them to carry out metabolism.
 

Nucleic Acids - Building Blocks

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are both polynucleotides, polymers of molecules called nucleotides. Nucleotides are composed of three components.
 

A Tutorial on Genes, Genomes, and Bioinformatics

DNA (deoxyribonucleic acid) is usually composed of two very long helical polymers of nucleotides. The nucleotides are composed of a sugar (deoxyribose), phosphate, and one of 4 nitrogenous bases, adenine (A), cytosine (C), guanine (G), or thymine (T). The two polymers are linked to each other by hydrogen bonds to form a double helix.
