DNA: Z vs. B form: which is inactive
ZZZZ is sleeping (inactive). B form is therefore active DNA.

DNA bond strength (nucleotides)
"Crazy Glue":
Strongest bonds are between Cytosine and Guanine, strong like Crazy Glue (3 H-bonds), whereas the A=T only have 2 H-bonds. · This is relevant to DNA replication, as the weaker A=T will be the site where RNA primer makes the initial break.

Nucleotides: purines vs. pyrimidines
Guardian Angels are Pure, with two Wings: G and A are Purines, with two Rings.

Pyrimidines are CUT from purines.
Pyrimidines are Cytosine, Uracil, Thiamine and are one ring structures.
Purines are double ring structures.
Amino Acids:The ten essential amino acids:
"These Ten Valuable Amino Acids Have Long Preserved Life In
Man."
(Threonine, Tryptophan, Valine, Arginine, Histidine, Lysine,
Phenylalanine, Leucine, Isoleucine, Methionine)

WBC Count:
"Never Let Momma Eat Beans(60, 30, 6, 3, 1)
Neutrophils 60%
Lymphocytes 30%
Monocytes 6%
Eosinophils 3%
Basophils 1%

The 5 sphincters found in the Alimentary Canal are APE OIL:
Anal, Pyloric, Lower Esophogeal, Oddi, and Ileocecum.

Sickle cell disease pathophysiology
SICKle cell disease is due to a Substitution of the SICKsth amino acid of the B chain.

Sickle cell anemia: mutation
"HbS isn't Very Good":
At Sixth position of HB beta chain, Valine is present instead of Glutamic acid.

Glycolysis steps

3-Phosphoglycerate
2-Phosphoglycerate (to)
Phosphoenolpyruvate [PEP] Pyruvate · 'Did', 'By' and 'Pies' tell you the first part of those three: di-, bi-, and py-.
· 'PrEPare' tells location of PEP in the process.

Blots: function of Southern vs. Northern vs. Western
SN0W DR0P:
· Match up the 1st word letter with 2nd word letter:
Southern=DNA
Northern=RNA
Western=Protein
· The 0's in snow drop are zeros, since there is no Eastern blot.
