The recombinase physically aligns short sequence elements on the lambda and bacterial dnas in order for recombination to occur.
a. both the lambda dna and the bacterial chromosome are cleaved, then recombined into a single circular dna.
b. following recombination, the lambda dna is referred to as a prophage.
c. the lambda dna is inserted at a random site in the bacterial chromosome.
d. the lambda dna and bacterial dna are recombined without the synthesis of any new dna sequence.

You have been asked to lead a demonstration for the undergraduate microbiology lab course about the uses of negative staining when studying bacteria. a "negative" stain does not stain the bacterial cell itself but stains the space between cells. under magnification, the acidic (negativelycharged) nature of the stain will be repelled by the negatively charged bacterial cell wall and willleave the cell colorless in a stained background. negative stains are used primarily to reveal the presence of negatively charged bacterial capsules; therefore, they are also called capsule stains. encapsulated cells appear to have a halo surrounding them. the negative stain procedure does not require heat fixation, which limits any chances of alteration in bacterial cell shape and size. the bacterial suspension is added to a drop of stain, such as nigrosin or eosin, and drawn across the glass slide using a coverslip. nigrosin staining-not safranin staining-of klebsiella pneumoniae will allow for the visualization of the cell shape and the determination of the presence of a capsule. true/false
