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:

Describe how changes to gene expression can cause cancer
Explain how changes to gene expression at different levels can disrupt the cell cycle
Discuss how understanding regulation of gene expression can lead to better drug design

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

Discuss the role of transcription factors in gene regulation
Explain how enhancers and repressors regulate gene expression

BI102: Survey of Molecular Life and Genetics is intended for one term of the introductory biology course for non-science majors taught at many two- and four-year colleges. The concepts of genetics, as they apply to the study of life, are introduced, including the principles of inheritance, genetics, and gene regulation.

This textbook incorporates the mandates found in Vision and Change and focuses on the non-content aspects of biology education that are just as important. Additionally, this book explicitly teaches the general education outcomes that we have identified as important for this class. This textbook pulls together biology content resources that are accessible for our community college non-major biology students, as well as resources to provide them with explicit instruction in the quantitative literacy, communication, and information literacy general education outcomes as they relate to the biology content they are learning.

The MIT Biology Department core courses, 7.012, 7.013, and 7.014, all cover the same core material, which includes the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. In addition, each version of the subject has its own distinctive material.

The MIT Biology Department core courses, 7.012, 7.013, and 7.014, all cover the same core material, which includes the fundamental principles of biochemistry, genetics, molecular biology, and cell biology. 7.013 focuses on the application of the fundamental principles toward an understanding of human biology. Topics include genetics, cell biology, molecular biology, disease (infectious agents, inherited diseases and cancer), developmental biology, neurobiology and evolution.Biological function at the molecular level is particularly emphasized in all courses and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. In addition, each version of the subject has its own distinctive material.  

Detailed analysis of the biochemical mechanisms that control the maintenance, expression, and evolution of prokaryotic and eukaryotic genomes. Topics covered in lecture and readings of relevant literature include: gene regulation, DNA replication, genetic recombination, and translation. Logic of experimental design and data analysis emphasized. Presentations include both lectures and group discussions of representative papers from the literature.
