Introduction to Molecular and Cellular Biology

Purpose of Course  showclose

This introductory course in biology starts at the microscopic level, with molecules and cells. Before we get into the specifics of cell structure and behavior, however, let’s take a cursory glance at the field of biology more generally. Though biology as we know it today is a relatively new field, we have been studying living things since the beginning of recorded history. The invention of the microscope was the turning point in the history of biology; it paved the way for scientists to discover bacteria and other tiny organisms and ultimately led to the modern cell theory of biology. You will notice that, unlike the core program courses you took in chemistry and physics, introductory biology does not have many mathematical “laws” and “rules” and does not require much math. Instead, you will learn a great number of new terms and concepts that will help you describe life at the smallest level. Over the course of this semester, you will recognize the ways in which the tiniest of molecules are involved in the way we go about our everyday lives. Note that this course is an alternative to BIO101B, and that you may choose to take either BIO101A or BIO101B in order to learn about molecular and cellular biology. These courses cover the same material but in a slightly different way.

Course Information  showclose

Welcome to BIO101A: Introduction to Molecular and Cellular Biology. General information about this course and its requirements can be found below.

Course Designers: Liang Wang, Johanna Choo, Ann Schlosser and Katie George

Primary Resources: This course is comprised of a range of different free, online materials. However, the course makes primary use of the following materials:

Requirements for Completion: In order to complete this course, you must review the material from all units (1–8). You will also be required to complete:
  • Unit 1 Quiz
  • Subunit 2.8 Problem-Based Learning Assessment
  • Unit 2 Quiz
  • Unit 3 Quiz
  • Subunit 4.7 Problem-Based Learning Assessment
  • Unit 4 Quiz
  • Unit 5 Quiz
  • Unit 6 Quiz
  • Unit 7 Quiz
  • Unit 8 Quiz
  • Final Exam
Note that you will only receive an official grade on your final exam. However, in order to adequately prepare for this exam, you will need to work through the required assignments listed above. 

In order to “pass” this course, you will need to earn a 70% or higher on the final exam.

Your score on the exam will be tabulated as soon as you complete it. If you do not pass the exam, you may take it again.

Time CommitmentCompleting this course should take you a total of 126 hours. Each unit includes a “time advisory” that lists the amount of time you are expected to spend on the subunits inside. These should help you plan your time accordingly. It may be useful to take a look at these time advisories and determine how much time you have over the next few weeks to complete each unit and then set goals for yourself. For example, Unit 1 should take you about 7.75 hours. Perhaps you can sit down with your calendar and decide to complete subunits 1.1 and 1.2 (a total of 1.25 hours) on Monday night, subunit 1.3 (a total of 5.5 hours) on Tuesday night, and so forth.

Tips/Suggestions: For more information on the topics covered in this course, please refer to BIO101B. As you read or watch the lectures, it may be helpful to take notes. It has been found that the physical act of writing helps a student retain material. These notes can also act as a study guide for the final exam.

Khan Academy  
This course features a number of Khan Academy™ videos. Khan Academy™ has a library of over 3,000 videos covering a range of topics (math, physics, chemistry, finance, history and more), plus over 300 practice exercises. All Khan Academy™ materials are available for free at www.khanacademy.org.
