BIO120: General Biology I

A complete guide to SNHU's BIO-120 General Biology I, covering mammalian cell structure and function, cellular reproduction and physiology, and Mendelian genetics, with laboratory exercises (BIO-120L) following lecture topics.

UndergraduateSNHUGeneral BiologyAPA 7th Edition

BIO-120 is a general biology course that includes mammalian cell structure and function, cellular reproduction and physiology, and Mendelian genetics, with laboratory exercises (BIO-120L) designed to follow the lecture topics — sharing its core content with SNHU's BIO-101 as a parallel introductory biology listing.

A shared foundation with BIO-101

BIO-120's description closely mirrors BIO-101's, both covering cell structure, cellular reproduction and physiology, and Mendelian genetics — reflecting SNHU's catalog pattern of maintaining parallel course numbers for genuinely equivalent content.

General Biology I as a program-specific entry point

As 'General Biology I,' this course typically serves as the entry point into a structured biology sequence (continuing into General Biology II), distinguishing its role in program sequencing from a standalone introductory course.

Worked example: recognizing a parallel course listing

  • Signal: BIO-101 and BIO-120 share nearly identical course description text
  • Interpretation: Rather than two different courses, this is genuinely equivalent content listed under two catalog numbers, likely tied to different program sequences
  • Lesson: Recognizing this pattern (also seen in Accounting, Taxation, and Marketing) helps students correctly map coursework to the right program sequence and study resources

Frequently asked questions

Is BIO-120 General Biology I a different course from BIO-101 Principles of Biology, or the same content under a different name?

The content is substantially the same — SNHU's own descriptions for both courses cover mammalian cell structure and function, cellular reproduction and physiology, and Mendelian genetics with an associated lab — confirming these are parallel introductory biology listings rather than two genuinely distinct courses. As 'General Biology I,' BIO-120 more explicitly signals its role as the entry point into a sequence continuing with General Biology II, which may be the main practical distinction between the two catalog numbers.

Why would SNHU maintain two catalog numbers (BIO-101 and BIO-120) for essentially the same introductory biology content?

Universities often maintain parallel course numbers to serve different degree program requirements or catalog eras without redesigning the underlying course — a Biology major's General Biology I requirement might specifically reference BIO-120's sequence position, while BIO-101 may serve as an equivalent general-education or different-program option covering the same fundamental content. For a student, the practical material — cell biology, reproduction, genetics — is the same either way.
