Assume that a given plasmid vector to be used in a cloning experiment contains 4000 base pairs of dna. assume also that the restriction endonuclease cuj cuts this plasmid at the following sites (starting from an arbitrary zero point): 1000, 1500, and 3000. given complete digestion of the plasmid with the endonuclease so that only linear fragments are produced, what sizes of dna are expected?

Indicate whether the following statements about the biases in the fossil record are true or false. a) inland species are more likely to be preserved than marine species b) organisms with hard body parts are more likely to be preserved than are those composed soft tissues. c) species that existed over a larger area are more likely to be preserved than species existing over a smaller area. d) organisms that lived very long ago are more likely to be found as fossils than organisms that lived relatively recently e) the fossils of larger organisms are more likely to be found than the fossils of smaller organisms
