Cell Biology

Course Description

Cell Biology is the study of the structure and function of eukaryotic cells, covering the basics of cellular function and biochemical foundations, cellular genetics and molecular biology, cell structure and function, cell signaling, and cytoskeletal organization and regulation. UWF notes that current topics in the news and disease case studies are used to apply the material to real-world situations.

Within the SCNS taxonomy, PCB is the Process Biology prefix. The University of West Florida publishes this at 3 semester hours through the Department of Biology, College of Science and Engineering.

⚠ This course is not in the statewide priority inventory and had no guide until now; it is written because it disposes of the queued PCB3103C, which UWF does not publish, and because its laboratory PCB3103L is queued and names this course.

Cell biology is the hinge course of an undergraduate biology degree. Genetics, molecular biology, developmental biology, immunology and physiology all assume it, and UWF's own prerequisite structure shows that plainly — PCB3103 is required by Immunology (PCB4233) and by Developmental Biology (PCB4253).

⚠ The chemistry prerequisite is not decoration. UWF requires organic chemistry (CHM 2210/L) alongside the second majors biology course, because membrane behaviour, protein structure and signalling chemistry are not describable without it. Students who scraped through organic chemistry should expect to revisit it here.

⚠ Why this guide exists under this number

Many Florida institutions carry this material as a single integrated C course. UWF runs a separate lecture and laboratory, each with its own SCNS number, and this guide documents the UWF lecture. Its laboratory partner is documented separately in this repository. ⚠ SCNS equivalency does not cross numbers, so transfer between the integrated and split forms is evaluated by hand — carry a syllabus in either direction.

⚠ The contact-hour figure is derived — the University of West Florida publishes none

UWF's catalog publishes a credit value in semester hours, the college and department, prerequisites and co-requisites, and fee notices. It does not publish contact hours, a lecture and laboratory split, or terms of offering for any course. Every contact-hour value in a UWF guide in this repository is derived. The figure applies the standard lecture convention of 15 contact hours per credit, giving 45 hours for 3 semester hours. Confirm the meeting schedule with the department.

Resources & Tools

• A cell biology text — Alberts' Molecular Biology of the Cell (or its Essential abridgement) and Lodish are the two standards; whichever the instructor assigns.
• NCBI Bookshelf (ncbi.nlm.nih.gov/books) — free; carries full text of Alberts and of Cooper's The Cell, which is a genuinely useful second explanation when the assigned text does not land.
• iBiology (ibiology.org) — free; short talks by the researchers who did the work, and unusually good on cytoskeleton and signalling.
• The Cell Image Library and the Allen Cell Explorer — free; seeing real micrographs rather than textbook cartoons changes how the organelles are understood.
• PubMed — free; the disease case studies in this course are all traceable to primary literature, and reading one paper properly is worth more than skimming ten.
• NCBI (ncbi.nlm.nih.gov) — free; PubMed, GenBank, BLAST and the rest of the toolkit, used professionally rather than only pedagogically.
• A UWF librarian — included in enrolment; an hour on database searching pays for itself across a whole degree.

Career Pathways

• Biological technicians — SOC 19-4021; the common direct entry point with a bachelor's degree.
• Biological scientists — SOC 19-1020; ⚠ independent research roles generally require a doctorate, and this is worth knowing early rather than late.
• Medical and clinical laboratory technologists — SOC 29-2011; ⚠ note that Florida licenses clinical laboratory personnel, so a biology degree alone does not permit bench work in a clinical laboratory — see the MLS prefix guides.
• Biotechnology and pharmaceutical industry — research associate, quality control and manufacturing roles; molecular technique competence is the entry currency.
• Environmental and conservation science — SOC 19-2041; Florida Fish and Wildlife Conservation Commission, water management districts, the Florida Department of Environmental Protection, and consulting firms.
• Marine and coastal science — a genuine Florida strength, including NOAA, Florida Sea Grant, Mote Marine Laboratory and the estuarine programmes on the Gulf coast near UWF.
• Public health laboratories — the Florida Department of Health Bureau of Public Health Laboratories.
• Science teaching — SOC 25-2031; ⚠ Florida K-12 teaching requires state certification that a biology degree alone does not provide.
• Professional and graduate pathways — medicine, dentistry, veterinary medicine, physician assistant, pharmacy, and research doctorates. This prefix is the core of a pre-health undergraduate plan.
• ⚠ An honest note on laboratory experience. Coursework laboratories are necessary and not sufficient — undergraduate research with a faculty member is what distinguishes a competitive graduate or professional applicant, and it is arranged by asking, usually earlier than students think.

Special Information

⚠⚠ PCB3103 and PCB3103L — how the pair is bound

• UWF publishes a Co-requisite: PCB3103 field on the laboratory entry. The lecture does not name the laboratory in return, so the binding runs one way — a student can take the lecture without the laboratory.
• ⚠ Many Florida institutions carry this material as a single integrated C course. UWF splits it into separately numbered lecture and laboratory, and SCNS equivalency does not cross numbers — so transfer between the two forms is evaluated by hand. Carry a syllabus in either direction.
• Take them together where the department intends it. The laboratory is designed to run alongside the lecture topics.
• ⚠ Budget for the pair. It is 4 semester hours in total, not 3, and the laboratory carries its own scheduled session.

⚠⚠ The asterisk in a UWF prerequisite means the course may be taken at the same time

• UWF marks a concurrent course with an asterisk, defined on the catalog's Course Information page as: "This course may be taken prior to or during the same term."
• ⚠ A prerequisite written WITHOUT an asterisk must be completed first; one written WITH an asterisk may be taken in the same term. Reading an asterisked prerequisite as sequential adds a term for no reason.
• UWF also uses an explicit Co-requisite: field, which is the stricter form — conventionally meaning the same term rather than prior-or-same. Both notations appear in this prefix.
• Confirm with an advisor; the registration system, not the catalog text, is what enforces it.

⚠⚠ Biology laboratory safety

• Know the location of the eyewash, safety shower, fire extinguisher and spill kit before you start work. That is a real instruction rather than a formality.
• ⚠ Eye protection and a lab coat are required, closed shoes are required, and never eat, drink or store food in a laboratory.
• Microbiological work is conducted at the containment level the organism requires, and ⚠ cultures are never opened outside the appropriate containment. Everything is autoclaved or disinfected before disposal.
• ⚠⚠ Human tissue, blood and body fluids are handled under Standard Precautions and are treated as infectious regardless of source. Sharps go into a sharps container at the point of use, and needles are never recapped by hand.
• Chemical hazards are real in a molecular laboratory — some nucleic acid stains and fixatives are mutagenic or carcinogenic, and phenol and chloroform cause chemical burns. Read the safety data sheet before first use, not after.
• ⚠ Ultraviolet transilluminators cause eye and skin burns; use the shield.
• Report every spill, cut and exposure immediately, however minor it seems.
• Tell the instructor if you are pregnant or immunocompromised; several standard laboratory materials and organisms warrant substitution.

Course format and position in the curriculum

• Lecture with examinations and problem work.
• ⚠ No "permission is required" marking appears anywhere in the PCB prefix, unlike UWF's clinical health prefixes — enrolment is gated by prerequisites rather than by cohort admission.
• UWF publishes no contact hours, lecture and laboratory split, or terms of offering for any course. Confirm the offering pattern with the department.

How Florida course levels affect transfer

The first digit of an SCNS number denotes the year of offering, not transferability. Courses at the 1000 and 2000 levels transfer transparently between Florida public institutions, and 3000 to 4000 is unproblematic since both are upper division. The boundary that actually matters is 2000 to 3000, where lower-division credit generally cannot satisfy an upper-division requirement. ⚠ For biology the specific transfer hazard is the split-versus-integrated question: UWF numbers lecture and laboratory separately where many institutions use one C course, and SCNS equivalency does not cross numbers. Carry a syllabus, and expect a transfer evaluation of either half to be done by hand.

PCB3103 is 3 semester hours at the University of West Florida.
