Complement proteins can bind to pathogens and
form a coating
enable them lifeless
cause them break apart
infect them with another pathogen
render them inert

It explains why rocks appear in layers

Is a method of dna sequencing first commercialized by applied biosystems, based on the selective incorporation of chain-terminating dideoxynucleotides by dna polymerase during in vitro dna replication.[1][2] developed by frederick sanger and colleagues in 1977, it was the most widely used sequencing method for approximately 40 years.
