A bacterium undergoes four rounds of replication. How many cells would result, and how many of those cells would still have part of an original DNA strand from the starting bacterium?

How would a scientist, observing a prokaryote and a eukaryote replicating their DNA, be able to distinguish the two? Group of answer choices Prokaryotic replication does not require a primer. Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication. DNA polymerases of prokaryotes can add nucleotides to both 3' and 5' ends of DNA strands, while those of eukaryotes function only in the 5' --> 3' direction. DNA replication in prokaryotic cells is conservative. DNA replication in eukaryotic cells is semi-conservative.

DNA polymerase occasionally incorporates the wrong nucleotide during DNA replication. If left unrepaired, the base-pair mismatch that results will lead to mutation in the next replication. As part of a template strand, the incorporated wrong base will direct the incorporation of a base complementary to itself, so the bases on both strands of the DNA at that position will now be different from what they were before the mismatch event. The MER-minus strain of yeast does not have a functional  mismatch excision repair system, but it has normal base excision repair and nucleotide excision repair systems. Which of the following statements is correct about differences in the mutation spectrum between MER-minus and wildtype yeast? More than one answer is correct. Options:   More point mutations will arise in MER-minus yeast.   Fewer point mutations will arise in MER-minus yeast as compared with wildtype.   Of the total point mutations that…
