A consortium comprising the Campbell Collaboration, the EPPI-Centre, Evaluation for Development Policy (EDePo), the International Initiative for Impact Evaluation (3ie),and LSHTM has been awarded the contract for this work.
RNA polymerase is the enzyme that assembles the individual nucleotides to create the RNA strand based on the DNA template. The RNA that is built here can actually be one of three different kinds. You may recall that the three different RNA types are mRNA, rRNA and tRNA. The type that we're concerned with here is mRNA.ere, initiation is the first phase of transcription, during which RNA polymerase attaches to the promoter and begins to build mRNA. The promoter for our keratin gene only exists on one strand of the DNA, which is how we know which strand is the antisense strand.
The RNA primer is a short strand of RNA that initiates DNA replication. So, the primer that initiates DNA replication isn't even made out of DNA! Don't get confused about the difference between the RNA primer and the RNA primase. Again, the enzyme that puts together the RNA primer is called RNA primase. Just remember that the one with -ase is the one that's the enzyme.
