Mean arterial pressure is not the simple mathematical average of diastolic and systolic pressures.

This is because a greater fraction of each cardiac cycle is spent in diastole than in systole.

RAG1 is the predominant recombinase; it forms a complex with the RSS that is stabilized by the binding of RAG2.

RAG2 by itself does not exhibit detectable RSS binding activity

RAG1 subunit and contains two aspartic acid residues and one glutamic acid residue (D600, D708, and E962, respectively). This active site “DDE motif” is found in many enzymes that cleave DNA
