It's hard to pick a starting point on where to begin in explaining our disdain for gender-reveal parties, but the name itself seems like a good one, in the fact that it's a complete misnomer. You are not revealing the gender of your baby; you are revealing the sex.
DNA Polymerase is a polymerase that synthesizes a DNA strand ... so it's used in DNA replication. RNA Polymerase is not used to form the primer-that is primases job. RNA Pol is used during transcription to synthesize the mRNA strand. EK does a decent job describing a primer.
In this section, we will disclose the differences between DNA polymerase and RNA polymerase. DNA strands are well formed when the deoxyribonucleotides undergo polymerization with the help of DNA polymerases which are thought to be enzymes that hasten the polymerization process.
