WebJan 21, 2024 · eling [14,15], we represent mRNA dynamics by a two-stage birth-death process (BDP). A gene locus generates nascent mRNA (unspliced or pre-mRNA) by some variant of a Poisson process. Af-ter an exponentially distributed delay with rate , nascent mRNA is converted to mature mRNA (spliced mRNA). Finally, after an exponentially … Webiis viewed as the birth rate while the transition rate iis viewed as the death rate when the process is in state i. When a birth occurs, the process goes from state ito state i+ 1. …

WebThe birth–death process (or birth-and-death process) is a special case of continuous-time Markov process where the state transitions are of only two types: "births", which increase the state variable by one and "deaths", which decrease the state by one.
