Biology

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

FLAT PEG = Hormones secreted by the Anterior Pituitary

F = Follicle stimulating hormone

L = Luteinizing hormone

A = ACTH

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

    P = Porifera

    C = Cnidarian

P = Platyhelminthes

N = Nematoda

A = Annelida

M = Mollusca

How to tell apart E and Z Configuration?

Z configurations have the highest priority groups on “Zee Zame Zide” (same side)

General Chemistry

Henderson Hasselbach Equation = Difficulty in remembering if the equation has a + or – sign and if the [A-] or [HA] was on top

Remember that being “positive (+)” will make someone go “Aha (like you’re laughing)”
