Targeted gene knockouts involve the deletion or disruption of a given gene. what method might be effectively used to knock out a gene in yeast? what method might be used in mice? why would the method used in yeast be ineffective in mice?

In order to determine the function of an unknown gene knockout technique is used. PCR based deletion strategy is used for gene knockout in the case of yeast, which is unicellular species and eukaryotic. On the other hand, in the case of a mouse, which is multicellular and eukaryotic, for gene knock out homologous recombination technique is used.  

The PCR based strategy is not appropriate for mice genes knockout, as mice are multicellular species and exhibit complex genome. While yeast constitutes some circular plasmids, known as 2 microns plasmids, which allows PCR based mutagenesis.  

sorry, is there a picture? i do not see any arrows.

wut? unius0123 wut?

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
