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.
However, the DNA sense strand itself is not used to make protein by the cell. It is the DNA antisense strand which serves as the source for the protein code, because, with bases complementary to the DNA sense strand, it is used as a template for the mRNA. Since transcription results in an RNA product complementary to the DNA template strand, the mRNA is complementary to the DNA antisense strand.
