Primase Makes short RNA primers which are short pieces of RNA to which dNTP’s are added.
DNA Polymerase An enzyme that adds dNTP’s (DNA Triphosphates) to a piece of nucleic acid.
DNA Polymerase III Main enzyme involved in the making of DNA. Has polymerase activity involved in adding primers to make a new strand DNA, also has exonuclease activity that removes bases that do nOt match. (PROOFREADING)

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
