One strand of a DNA molecule has the base sequence 5’-GGTCAGCAT-3’. The complementary base sequence on the other strand of DNA will be 3’-GTGAAT-5’. Identify if the follow would or would not be likely to cause a mutation:
-addition of nucleotides to the 3’ end of the growing strand
-insertion of a mismatched nucleotide into a DNA strand
-unwinding of the DNA strand
-synthesis of short stretches of DNA

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
