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.
The size of an individual gene or an organism's entire genome is often measured in base pairs because DNA is usually double-stranded. Hence, the number of total base pairs is equal to the number of nucleotides in one of the strands (with the exception of non-coding single-stranded regions of telomeres).
