Confidence votes 2.6K. A composite volcano is built up from alternate layers of ash and lava. It has steep sides because when it erupts it lava is thick and viscous (andesitic) meaning that it does not travel great distances and stays on the side of the volcano. An example is Mount Vesuvius (which destroyed Pompeii).onfidence votes 2.6K. A composite volcano is built up from alternate layers of ash and lava.

Primase is an enzyme that creates a primer on a DNA strand by adding RNA nucleotides to the strand according to the DNA template sequence. This process occurs during DNA Replication. If all this sounds complicated, don't worry.We'll break it down below, starting with how DNA replication works.fter the DNA is unzipped, by an enzyme called helicase, it is time for primase to come in. Primase starts off the creation of the new strand of DNA by adding the first nucleotide building blocks at a site called the origin of replication. This will be the starting point for creating the new side of the DNA zipper.
