Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Explain how the structure of DNA reveals the replication processDescribe the Meselson and Stahl experiments

By the end of this section, you will be able to:Discuss the similarities and differences between DNA replication in eukaryotes and prokaryotesState the role of telomerase in DNA replication

By the end of this section, you will be able to:Explain the process of DNA replication in prokaryotesDiscuss the role of different enzymes and proteins in supporting this process

The goal of this course is to teach both the fundamentals of nuclear cell biology as well as the methodological and experimental approaches upon which they are based. Lectures and class discussions will cover the background and fundamental findings in a particular area of nuclear cell biology. The assigned readings will provide concrete examples of the experimental approaches and logic used to establish these findings. Some examples of topics include genome and systems biology, transcription, and gene expression.

This is a remix of the RIce University Open Stax... I made changes to add a numbered list to the steps for accessiblity and added images and attributions.By the end of this section, you will be able to:Explain the process of DNA replication in prokaryotesDiscuss the role of different enzymes and proteins in supporting this process

Sal reflects on the amazing speed and precision with which DNA replication takes place.

Introduction to transcription including the role of RNA polymerase, promoters, terminators, introns and exons.
