BIOL1004 Explained: ANU, Adelaide & Other Unis

BIOL1004 is not one course. At ANU it is Biology 2: Molecular and Cell Biology, a second-semester prerequisite for later biology majors; at Adelaide it is Biology 1B: Evolution and Diversity of Organisms. Murdoch and several US colleges reuse the code too. Here is how to identify your version and what each one covers.

BIOL1004 is not a single course. The code points to different first-year biology subjects depending on the university, so the first task for any student searching it is identifying which institution's BIOL1004 they mean.

At ANU it is Biology 2: Molecular and Cell Biology. At Adelaide University it is Biology 1B: Evolution and Diversity of Organisms. Same code, different content, different semester.

Which course is BIOL1004?

Course codes are not standardised across Australian universities. Each institution assigns its own, so a code like BIOL1004 can sit in molecular biology at one campus and evolutionary biology at another.

The table below maps the main versions. Confirm yours by the university name, not the code alone.

University Course title Semester Focus
ANU Biology 2: Molecular and Cell Biology Semester 2 Molecular and cell biology
Adelaide University Biology 1B: Evolution and Diversity of Organisms Semester 1 Evolution, ecology, diversity
Murdoch University Foundations of Bioscience Practice Lab and bioscience skills

What is BIOL1004 at ANU?

At the Australian National University, BIOL1004 is Biology 2: Molecular and Cell Biology. It introduces the molecular and cellular side of modern biology, starting with the molecules that drive life.

The course covers DNA, proteins, and carbohydrates, then how each functions inside the cell. It runs in Semester 2, the second of ANU's two first-year biology courses.

Its importance is structural. BIOL1004, together with CHEM1101 and CHEM1201, is a prerequisite for many later courses in ANU's Research School of Biology, so a weak result here can close doors in second and third year.

Assessment carries hurdle requirements: recent offerings required students to reach at least 40% across the combined mid-semester and final exams to pass, regardless of other marks. Confirm the current structure on ANU's Programs and Courses page, since weightings shift between years.

What is BIOL1004 at Adelaide?

At Adelaide University, BIOL1004 is Biology 1B: Evolution and Diversity of Organisms, a 1000-level course worth 6 credit points, offered in Semester 1. It sits on the evolutionary and organismal side of biology rather than the molecular side.

The content spans evolution, population genetics, ecology, and the diversity of living organisms. It pairs with Adelaide's other first-year biology course rather than duplicating it.

You can see the full topic map and the repeated final-exam question types on our Adelaide BIOL1004 page, and browse other first-year units in the Adelaide course catalogue.

Where else is BIOL1004 used?

The code travels beyond ANU and Adelaide. Murdoch University uses BIOL1004 for Foundations of Bioscience Practice, a skills-focused unit built around laboratory work and scientific method.

Several United States colleges also use BIOL 1004, usually for an introductory or general biology subject. Middle Georgia State and others apply it to first-year survey courses with no relation to the Australian versions.

The practical takeaway is the same in every case. Search the code together with your university name, since a study guide, past paper, or tutoring resource for one BIOL1004 is useless for another.

How do you study BIOL1004?

The right method depends on which BIOL1004 you are in, because the two main Australian versions test different skills. Molecular and cell biology rewards mechanism understanding; evolutionary biology rewards conceptual breadth.

For the ANU molecular course, the load is process-heavy: replication, transcription, translation, and signalling pathways. AskSia's AI tutor walks a multi-step mechanism three different ways until one explanation lands, which matters more than rote recall on hurdle exams.

For either version, the volume of terminology is the trap. Auto-built Flashcards with spaced repetition, tuned to your exam date, keep DNA, protein, and taxonomy terms from fading across a 12-week semester.

Map the course with AskSia's Concept Map to see how molecular foundations feed cellular function and, in the evolutionary version, how genetics underpins population change. The dependencies are what later courses assume you retained.

Frequently Asked Questions

What is BIOL1004?

BIOL1004 is a first-year university biology course, but the exact subject depends on the institution. At the Australian National University it is Biology 2: Molecular and Cell Biology, a Semester 2 course covering DNA, proteins, carbohydrates, and cell function. At Adelaide University it is Biology 1B: Evolution and Diversity of Organisms, a 6-credit-point Semester 1 course on evolution, ecology, and biodiversity. Murdoch University uses the same code for Foundations of Bioscience Practice, and several US colleges use BIOL 1004 for introductory biology. Because course codes are not standardised between universities, the code alone is not enough to identify the content. Always search BIOL1004 alongside your university's name, and confirm the title and semester on that university's current course handbook before buying textbooks or study resources.

Is BIOL1004 at ANU hard?

ANU's BIOL1004, Biology 2: Molecular and Cell Biology, is considered demanding because it is content-dense and carries hurdle requirements. Recent offerings required students to score at least 40% across the combined mid-semester and final exams to pass, independent of assignment marks, so the exams cannot be skipped. The difficulty is concentrated in mechanism-heavy topics: replication, transcription, translation, and cell signalling, where questions are multi-step rather than recall. The course is also a prerequisite, together with CHEM1101 and CHEM1201, for many later Research School of Biology courses, which raises the stakes of a marginal pass. Start mechanism practice early rather than memorising in the final weeks, and check the current assessment weightings on ANU's Programs and Courses page, as the hurdle and exam split can change between years.

What semester is BIOL1004?

It varies by university, which is one reason the code causes confusion. At ANU, BIOL1004 runs in Semester 2, positioned as the second first-year biology course after BIOL1003. At Adelaide University, BIOL1004 runs in Semester 1. This matters for planning: an ANU student and an Adelaide student searching the same code are preparing for exams in different halves of the year. Adelaide's exam window for Semester 1 2026 falls in June, while an ANU Semester 2 course is examined in November. Check the teaching period on your own university's course page, since enrolment, census, and exam dates all follow the semester the course is offered in, not the code number.

Is BIOL1004 a prerequisite for other courses?

At ANU, yes. BIOL1004, alongside CHEM1101 and CHEM1201, is listed as a prerequisite for many later-year courses in the Research School of Biology, so it functions as a gateway into the biology major rather than a standalone elective. A fail or a withdrawal can delay your progression into second and third-year courses by a full year, since the course runs once annually. At other universities the prerequisite chains differ, and a course with the same code may carry no downstream dependencies at all. Before dropping or deferring BIOL1004, check the prerequisite tree for your intended major on your university's course planner, and map the affected later courses so you understand the knock-on effect on your degree timeline.

What is the difference between ANU and Adelaide BIOL1004?

They are different branches of biology. 

ANU's BIOL1004 is Biology 2: Molecular and Cell Biology, focused on the molecular machinery of cells, DNA, proteins, and metabolic pathways, and it runs in Semester 2. 

Adelaide's BIOL1004 is Biology 1B: Evolution and Diversity of Organisms, focused on evolution, population genetics, ecology, and biodiversity, and it runs in Semester 1. 

The ANU version leans quantitative and mechanism-based; the Adelaide version leans conceptual and comparative. A study resource built for one will not match the other's exam. Identify your version by university name first, then source past papers, tutoring, and notes specific to that institution rather than relying on shared material tagged only with the code.
