Nucleotide changes, particularly those at the third position of the codon, that do not alter the amino acid sequence are called synonymous substitutions.

Nucleotide changes in a gene that alter the amino acid sequence of a protein are referred to as non-synonymous substitutions.

The C5b678 complex can create a small pore, 10 Å in diameter, and formation of this pore can lead to lysis of red blood cells, but not of nucleated cells.

10 to 19 molecules of C9 can be bound and polymerized by a single C5b678 complex. The completed MAC, which has a tubular form and functional pore diameter of 70 Å to 100 Å.
