What are the differences between DNA and RNA
Transcription of DNA
Transcription of RNA
What is the differnce between transcription and translation
DNA and RNA are polymers of what biological molecule nucleotides
What polymers to nucleotides form? Nucleic acids
What bond binds nucleic acids? phosphodiester
What nucleotides are purines in DNA and RNA Adenine and Guanine

DNA and RNA contain _____ groups sugar, DNA lack an OH on 2'
true or false, Phosphates can attach to the sugar of the nucletide? true
What do nucleosides consist of ? base + sugar
What do nucleotides consist of ? base + sugar + phosphaTe

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.
