Producing the allergen-free cat will require knocking out this gene so that the protein will not be produced.
It requires knocking down two wings of the city's 100-year-old train station, one of the few buildings to survive heavy bombing during World War II, and cutting down about 300 trees, some centuries old.
This type of business development requires knocking on doors and navigating serious negotiations.
Controlling when tomatoes turn from green to red requires knocking out the gene that adds flavor.
Doing so requires knocking out a gene and observing the effect on phenotype, but the few methods available to do that, such as antisense, ribozymes, or aptamers, were painstaking or imprecise, or both.
And making room for a massive, undulating new structure by Zumthor along Wilshire Boulevard would require knocking down four of the oldest buildings on the museum's campus, including three designed in the early 1960s by prominent L.A. modernist William Pereira.
Studying the functional role of these piRNAs would require knocking down the piRNA production from all these specific genes without changing their protein expression.
Determining the molecular details of RNAi itself require knocking out many of the genes involved, including Dicer and other Argonaute proteins, all members of the PAZ domain protein family [ Table 1; for example, see Knight and Bass (2001)].
3) Showing a causal relationship between activation of V1R e and j members and mating behavior is beyond the scope of the current study, as this would require knocking out these genes.
