polymerases

Also present in the nucleoplasm are proteins known as polymerases, which pluck nucleotides from the soup as needed when copying DNA.

The Speculist: Better All The Time #22 2005

Human cells contain enzymes - called polymerases - that perform the process of copying DNA.

When a cell divides and DNA needs to be replicated, the double helix is split, and enzymes called polymerases use each of the two halves as a template for an new opposing strand; the base pairing rules ensure that the copying is exact, except for rare errors.

Ars Technica 2009

This is not the case with many other actual difference makers, such as polymerases, which are more like on/off switches (with respect to differences in linear sequences).

Molecular Genetics Waters, Ken 2007

Telomerase extends telomere DNA, providing a platform that enables DNA polymerases to copy the entire length of the chromosome without missing the very end portion.

The 2009 Nobel Prize in Physiology or Medicine - Press Release 2009

So, we took examples from people that had worked on other kinds of polymerases and made our best creative guesses about what kind of experiments to do.

When Turner added the final ingredient, the ZMWs burst into a riot of sparkling lights—like flashbulbs at the first pitch of the World Series—as the polymerases jumped into action.

The $1,000 Genome Kevin Davies 2010

The number of steps in the sequence is, in theory, limited only by the number of distinct bacterial RNA polymerases.

We found, to the contrary, that RNA polymerases are capable of reading right through a nucleosome.

Roger D. Kornberg - Autobiography 2007

A signal is generated through the transcription (mRNA) of DNA (this is a very simplified version which omits detailing the many components of successful signaling i.e. promotor regions, RNA polymerases, transcription factors and more) tRNA and tRNA aminoacyl synthetases would be components involved in a translation process involving codons and anti-codons, the ribosome, the destination.
