What is an enzyme, and what suffix do enzymes end in Proteins, and they end in -ase
What are the 4 enzymes important for DNA replication, and what are their functions DNA Helicase unwinds the DNA, RNA Primase makes RNA primers on both strands, DNA Polymerase builds new strands in the 5'>3' direction, and DNA Ligase seals the DNA fragments
What is the enzyme important for RNA synthesis, and what is its function RNA Polymerase, and it binds with DNA to help create RNA

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

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.
