Biology 101: Intro to Biology - A Free Course

Biology 101: Intro to Biology is designed to be used to prepare you to earn real college credit by passing the Biology CLEP exam.

This course covers topics that are included on the exam, such as genetics, physiology, plant and animal biology, ecology and evolution.

Use it to help you learn what you need to know about biology topics to succeed on the exam.

The biology instructors are experienced and knowledgeable educators who have put together comprehensive video lessons in categories ranging from Mendel’s first law to the anatomy of the brain.

Each category is broken down into smaller chapters that will cover topics more in-depth.

These video lessons make learning fun and interesting. You get the aid of self-graded quizzes and practice tests to allow you to gauge how much you have learned.

Additionally, learn about the cell wall, central vacuole, prokaryotic and eukaryotic cells and the lytic and lysogenic cycles of viruses.
DNA Replication: Processes and Steps	Find out about DNA replication and learn how helicase unwinds the DNA double helix in preparation for replication, how Okazaki fragments of the lagging strand DNA are replicated and the definition of replication bubbles.
The Transcription and Translation Process	Study protein synthesis in cells, transcription of mRNA, regulation of gene expression, how an operon controls transcription, the genetic code that translates RNA into amino acids, codon recognition and the translation of mRNA to protein.
Genetic Mutations	Learn about point mutations and the effects of mutation on protein function.
Metabolic Biochemistry	Examine cellular respiration, redox reactions, glycolysis, the citric acid cycle, the electron transport chain, lactic acid, alcoholic fermentation and photosynthesis.
Cell Division	Take a look at the genome, the structure of chromosomes, the cell cycle, DNA packaging, features of a chromosome, mitosis, cytokinesis, asexual versus sexual reproduction and meiosis.
Plant Biology	Study the different types of plants – vascular, nonvascular, monocot and dicot. Also learn about the structure of plant stems, the apical meristem, primary shoot system growth, the lateral meristem, secondary shoot system growth, the structure of leaves, primary root tissue, root hairs, primary roots, lateral roots, nitrogen fixation, xylen, phloem, flowers and pollination.
Plant Reproduction and Growth	Examine the life cycles of moss, fern, gymnosperm and angiosperm. Additionally, take a look at asexual plant reproduction, tropisms, photoperiodicity, seasonal growth cycles and plant hormones.
