BIO205A Summer 2026: Intro

Also some recap from week 3DNA barcoding, 3 parts- what is BLAST?Gram stainingSensory, eye dissection, visual, auditory, equilibrium testsWeek 4 DigestiveAlimentary canal and accessory organs- identifyHistological features of the regions associated with different processes UrinaryAnatomy- kidneysNephron parts, what are the processes of urine formation?Glomerulus, simple squamous, simple cuboidal in the tubuleUrine analysis, what is normal, what is not

Gram stainDNA barcoding: DNA extraction, PCR, blast (next week)SensoryEye structureRespiratory: histology, lung volumes

Summary of week 2 material. Emphasis on nervous system, reflexes, blood tests, circulation, heart dissection, and ECG. On the micro side, screening for antibiotic producers and streaking.

What to expect before coming to class in week 2?Friday micro: screening for antibiotic production Friday AP: Nervous and endocrineNerve tissue slidesCNS/PNSBrain structures (includes sheep brain dissection)Spinal cord (dissection)Physiology: reflexes recordingSaturday micro: Streaking techniqueSaturday AP: CardiovascularBlood: cells and blood typesCardiac muscleHeart structure (plus dissection)ECG

Going over what we did during the first week!

Audio episode about what to expect the first week of the course, and what you can do to prepare better.

This episode is dedicated to the current students of BIO205A at National University or for other students interested in trying this course in the future.

Quick guide on how to look up a 16S sequence using the BLAST tool.Applies to BIO203A and BIO205A.

Quick rundown about what is similar and what is different between Staphylococci and Streptococci, and how you differentiate S. aureus from other Staph, as well as some of the characteristics of the main Streptocci.
