Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

List the steps of replication and explain what occurs at each step
Describe the lytic and lysogenic cycles of virus replication
Explain the transmission of plant and animal viruses
Discuss some of the diseases caused by plant and animal viruses
Discuss the economic impact of plant and animal viruses

Met deze simulatie kunnen gebruikers verkennen hoe een interessant
eiwit, rood fluorescerend eiwit, gezuiverd kan worden uit cellysaat met
behulp van hydrofobe kolomchromatografie.

This simulation allows users to explore how a protein of interest, red
fluorescent protein, can be purified from cell lysate using hydrophobic
column chromatography.

This video animation describes the effect of the detergent SDS on cellular membranes. SDS is a crucial reagent in SDS sample buffer that is used in protein gel electrophoresis (SDS-PAGE).
