During dna transposition by the cut-and-paste mechanism, the transposase cuts the two strands of the target site dna several nucleotides apart. cellular repair enzymes fill in these overhangs, resulting in the formation of during dna transposition by the cut-and-paste mechanism, the transposase cuts the two strands of the target site dna several nucleotides apart. cellular repair enzymes fill in these overhangs, resulting in the formation of the synaptic complex. a poly-a sequence. target site direct repeats. long terminal repeats. inverted terminal repeats.

Which statement about dna replication is true? a. eukaryotes only have one circular chromosome that unwinds at multiple locations. b. eukaryotes can only replicate one segment of a chromosome at a time. c. prokaryotes can only replicate their single circular chromosome in the nucleus. d. prokaryotes only have one origin of replication to initiate replication.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
