Transcript of Timeline of Educational Reform. U.S. Supreme Court announces its decision in the case of Brown v. Board. of Education of Topeka, ruling that separate educational facilities are inherently unequal, thus overturning its previous ruling in the 1896 case of Plessy v. Ferguson.
The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way. During DNA replication the leading strand is replicated continuously whereas the lagging strand is replicated in segments known as Okazaki fragments.
If the main purpose of a plasmid is to serve as a vehicle for genes of interest, we need to be able to insert the human insulin gene into the plasmid. This is the purpose of a multiple cloning site. A multiple cloning site is the location in a plasmid where a sequence of DNA, typically a gene, can be inserted.enetic engineering, by its nature, requires DNA be stored until needed and moved at will from the test-tube environment to a cellular environment or vice-versa. A DNA plasmid makes it easier to accomplish this goal.
