DNA

TermDefinition
DNA deoxyribonucleic acid; contains information about an organism's growth and function
gene sequence of DNA that codes for a protein and thus determines a trait
chromosome gene-carrying structure found in the nucleus. Each chromosome consists of one very long DNA molecule and associated proteins.
Franklin large DNA spiral was made of 2 spirals
Watson & Crick created model of DNA molecule
sides of DNA ladder made of deoxyribose and phosphate molecule
rungs of DNA ladder guanine, cytosine, adenine, thymine (G, C, A, T)
nitrogen bases guanine pairs with cytosine; adenine pairs with thymine ( G + C, and A + T)
steps of DNA replication 1) enzyme separates DNA sides 2) new bases pair with bases on original DNA 3) two new identical DNA molecules are produced
RNA ribonucleic acid
3 ways RNA and DNA differ 1) RNA has a half ladder 2) RNA has the base uracil instead of thymine 3) RNA contains sugar ribose
mutation any permanent change in DNA sequence of a gene or chromosome (Helpful, Harmful, Neutral)
causes of mutations outside factors such as xrays, sunlight, chemicals

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.
