P bodies are dense cytoplasmic domains many times the size of a ribosome. They are sites of translational repression that contain no ribosomes or translation factors. They are also major sites of mRNA degradation in the cytoplasm. Exon-junction complexes upf complex functions in nonsense-mediated decay and induces degradation of the mRNA by P body–associated 5′→3′ exoribonuclease XRN1

Physical sequestration of the origin, delay in remethylation, competition for DnaA binding, hydrolysis of DnaA- bound ATP, and repression of dnaA transcription are the key steps to regulate initiation.

A recessive allele (a) that causes a genetic disease has a frequency (q) of 0.01. If the population mates randomly (F = 0), the frequency of individuals affected by the disease (aa) will be q = 0.01 = 0.0001.

However, if F = 0.25 expected frequency of the aa is .0026.
