Describe the role that integrase plays during the insertion of λDNA into the host chromosome.

what is the placentation type (axils, basal, parietal, free-central, or marginal) of avocado?

1) Assume you have an operon that is repressible. In this case, the rate of synthesis of repressor protein must depend on the level of a) co-repressor b) inducer c) both d) neither

I can follow along to this response but can you re explain by not plagirising? can you paraphrase?

Give one examples of mutaion?

Phage Mu may be integrated into E. coli genomic DNA via Select one: O a. recombination catalyzed by homologous recombination enzymes. O b. conservative transposition O c. integration catalyzed by integrase. d. replicative transposition

In 1965, Jon Beckwith and Ethan Signer devised a method of obtaining specialized transducing phages carrying the lac region. They knew that the integration site, designated att80, for the temperate phage φ80 (a relative of phage λ) was located near tonB, a gene that confers resistance to the virulent phage T1: tonB att80 They used an F ′ lac+ plasmid that could not replicate at high temperatures in a strain carrying a deletion of the lac genes. By forcing the cell to remain lac+ at high temperatures, the researchers could select strains in which the plasmid had integrated into the chromosome, thereby allowing the F ′ lac to be maintained at high temperatures. By combining this selection with a simultaneous selection for resistance to T1 phage infection, they found that the only survivors were cells in which the F ′ lac had integrated into the tonB locus, as shown here: tonB F lac att80 This result placed the lac region near the integration site for phage φ80. Describe the subsequent…
