WHAT IF? Would you expect the plastid DNA of photosynthetic dinoflagellates, diatoms, and golden algaeto be more similar to the nuclear DNA of plants (domainEukarya) or to the chromosomal DNA of cyanobacteria(domain Bacteria)? Explain.
Yes or no ? No explanation
does plasmid dna synthesize in the 5'to3' direction?
situ hybridization, northern blot and microarray can assess in situ hybridization of gene expressions in planarians.
does luciferase rnai effect planarians development?
WHAT IF? Stechmann and Cavalier-Smith wrote that their conclusions are“valid only if the genes fused just once and were never secondarily split.” Whyis this assumption critical to their approach?

- 14) Hybridization was not originally recognized as a mechanism of speciation by either Darwin or the researchers of the "new synthesis". However, today there are many examples of species that have originated through hybridization. What is the best explanation for why we have so many examples of species originating through hybridization? A) Hybridization is more likely to occur in regions where scientists have put in more effort studying speciation B) Hybridization occurs fairly regularly, and when it leads to new species only takes a few generations, which is fast enough for researchers to see fairly easily C) Hybridization is fairly easy to study in captivity D) Hybridization has been carried out frequently by farmers attempting to produce new, better species to grow 15) Anthropologist who study human evolution genetically have determined that populations of our species have gone through"founder effect" type events.
