BS in Biochemistry, Effective Fall 2025

The BS in Biochemistry is intended for those with an interest in the chemistry of living systems. It is an interdepartmental major for students interested in topics that intersect both chemistry and biology and is offered jointly by the Department of Chemistry and the  Department of Biology.

Program Requirements and Policies

• Seventeen courses and their accompanying labs are required to complete the major. 
• No major course may be taken Pass/Fail.
• If you have more than one major, please see Bulletin for rules on double-counting courses across majors.
• A student majoring in Biochemistry may not declare any minor in Chemistry. 
• Note: A student majoring in Biochemistry no longer needs to complete Biology or Chemistry research to be eligible for a summa cum laude degree.

* Effective Fall 2025, the Biochemistry major requires either Chem31: Physical Chemistry OR Chem 35: Biophysical Chemistry (Recommended). Please note that Chem 31 has Math 34 and Phys 2 as prerequisites. Math 34 may be used as an elective course. Chem 35 requires only Math 32 and Phys 1 or 11 as prerequisites. 

** Starting with the incoming class of 2027, please note that Bio 13 and 15 are linked and must be taken concurrently for Biochemistry majors. If you are an A&S student, both courses must be added to your SIS cart when enrolling in Bio 13 & 15. Engineering students should be aware that there are restrictions on which majors and years are permitted to enroll in this course. BME students should enroll in BME 33 instead; some SoE majors may take Bio 13 without Bio 15. 

*** Effective for classes graduating after May 2024, the Biochemistry major will require at least one semester of a graded, experiential laboratory course. This laboratory requirement can be fulfilled in one of two ways: 

1. Students complete Chem 43 & 45 and any of the experiential laboratory research requirements. 

2. Students complete Chem 42 and one of the following laboratory courses that include molecular biology techniques: Bio 50, Bio 52, Bio 54, ChBE 163, or a graded independent research course in Biology (Bio 193, 194, 199) or petition to count graded research done in the Chemistry Department (Chem 82 or higher) that includes a biological component. 

Course Planning for Biochemistry Majors

The Biochemistry Major is flexible and can be completed following many possible tracks. Still, care must be taken when planning schedules to ensure that certain course sequences are taken in the correct order. For example, in the Biology Department, Bio13 & 15 is a required prerequisite for Bio41, and Bio41 is a required prerequisite for Bio105. On the Chemistry side, Chem 1/11 must be taken before Chem 2/12; Chem 2/12 is a required prerequisite for Chem 51 and Chem 43 & 45 (or 42); and Chem 51 is a required prerequisite for Chem 171, which must be taken before Chem 172. Please note that Chem 35 requires Chem 2/12, Math 32, and Phys1/11 as prerequisites, while Chem 31 requires Chem 2/12, Math 34, and Phys1/11 as prerequisites with Phys2 as a pre/co-requisite. This list is not comprehensive, so please be sure to review the prerequisites for any courses you are considering when planning your schedule. You will also want to carefully check the times these courses are offered. For example, Bio 41 and Chem 12 are generally offered during the same class block during the Spring semester, these classes cannot be taken in the same semester

To assist in your planning process, the tracks below represent a few options that would allow students to complete a Biochemistry major within 8 semesters. Please note that there are many other possible paths one could take through the Biochemistry major. In particular, the timing of the courses listed under “Other Required Courses” is p

articularly flexible. A listing of courses typically offered in Fall, Spring, and Summer can be found below the sample pathways:

Courses typically offered in Fall semesters: Bio 13 & 15, Bio 50, Bio 105, Chem 1/11, Chem 2, Chem 51 & 53, Chem 172, Chem 31, Chem 43 & 45, Chem 157, Math 32, Math 34, Phys 1/11, Phys 2/12

Degree Sheet Submission Instructions

For seniors who plan to graduate in May and whose major advisors are Chemistry faculty, follow the instructions below to apply for graduation, complete a Biochemistry Major Degree Sheet, and submit Graduation Materials. 

If your major advisor is a Biology faculty member, please reach out to your major advisor and the associate chair of Biology and follow the instructions provided by the Biology Department. 

1. Login to your SIS account and go to your “academics” tab, and choose the last menu item, which is “apply for graduation”. Choose your “time/term of graduation” as May (August for those who are completing the requirements after summer school). 
2. For the distribution requirements, follow the instructions in the above link to see if they are satisfied. 
3. For the Biochemistry requirements, please find the form from our department website and fill it out: https://chem.tufts.edu/resources/forms-and-guides
4. Once you fill out your degree sheet and SIGN, please email the pdf of the completed form to your advisor no later than Wednesday, November 20*. Please use Lastname_Firstname_DegreeSheet as your file name. Your advisor will go over the courses, check the grades, then send it to Department Chair via Box to sign it. 

When the form is complete you will be notified by a member of Chemistry staff and you will add the signed form to your package and send to registrar via SIS upload.

Instructions from the registrar to upload Graduation Materials.

*If you submit your signed form to your advisor after 11/20, we cannot guarantee that your signed degree sheet will be back in time for you to submit your graduation packet by the 11/30 deadline.
