Biology Mnemonics To Know For the DAT

Mnemonics are a great tool to memorizing large amounts of information quickly. Here are a couple I used to answer some questions on the DAT:

Cell Division / Cell Biology

Cell Replication Phases = I Pee on a MAT

I = Interphase
P = Prophase
M = Metaphase
A = Anaphase
T = Telophase

Metaphase = “M” = Middle

All chromosomes line up in the middle of the cell at the metaphase Plate

Anaphase = “A” = Apart

Sister chromatids are pulled Apart

Pyrimidines = CUT the PYE (pyrimidine)

C = Cystine
U = Uracil
T = Thymine

Purines = Pure (purine) Silver (Ag)

A = Adenine
G = Guanine

Ion Movement Across a Membrane = Salted Bananas

3 Sodium ions (“salt”) flow out of the cell and 2 Potassium ions (“bananas”) into the cell

Central Dogma = Roast Turkey Later

R = Replication
T = Transcription
L = transLation

Anatomy & Physiology

Sequence of the Small Intestine = The small intestine “Don’t Just Injest”

D = Duodenum
J = Jejunum
I = Ileum

COPS = Four Types of Myelinated Cells in the Nervous System

Central NS: Oligodendrocytes
Peripheral NS: Schwann Cells

Epidermis Layers = Come Lets Get Sun Burned

C = Corneum
L = Lucidum
G = Granulosum
S = Spinosum
B = Basal

Liver Functions = PUSH DoG

P = Protein synthesis
U = Urea synethesis
S = Storage
H = Hormone synthesis
D = DetOxification
G = Glucose and fat metabolism

Afferent vs. Efferent Neurons = SAME DAVE

S, A= Sensory, Afferent
M, E = Motor, Efferent
D, A = Dorsal, Afferent
V, E = Ventral, Efferent

FLAT PEG = Hormones secreted by the Anterior Pituitary

F = Follicle stimulating hormone
L = Luteinizing hormone
T = Thyroid stimulating hormone
P = Prolactin
E = Endorphins
G = Growth hormone

Calcitonin/Parathyroid Differentiation

CalciTONin = “Tone it down” = Decrease in blood calcium
Parathyroid is the opposite


Four Chordate Features = Do Not Pinch People

D = Dorsal hollow nerve cord
N = Notochord
P = Pharyngeal gill slits
P = muscular Post-anal tail

King Phillip Came Over From Great Spain (or King Phillip Came Over For Great Soup)

K = Kingdom
P = Phylum
C = Class
O = Order
F = Family
G = Genus
S = Species


Animal Kingdom Phylums = How to remember which are acoelomates, pseudocoelomates, and coelomates = Privileged Children Play Nicely and Maturely Always Ensuring Cooperation

P = Porifera
C = Cnidarian
P = Platyhelminthes
N = Nematoda
A = Annelida
M = Mollusca
A = Arthropoda
E = Echinodermata
C = Chordates
* Rotifers are pseudocoelomates (not included in this mnemonic)


Order of White Blood Cell Abundance in Blood = Never Let Monkeys Eat Bananas

N = Neutrophils (most abundant)
L = Lymphocytes
M = Monocytes
E = Eosinophils
B = Basophils (least abundant)


Hardy-Weinberg Requirements = Large Random M&M

L = Large population
R = Random mating
M = no Mutation
N = no Natural selection
M = no Migration

Biology Lab Techniques

Southern Northern and Western Blot = SNOW DROP

S = Southern blot = D = DNA detection
N = Northern blot = R = RNA detection
O = –
W = Western blot = P = Protein detection
