QuestionAnswer
how many strands does DNA have 2 double
how many strands does RNA have 1 single
where is DNA located in the cell nucleus; doesn't move out
where is RNA located in the cell nucleus and cytoplasm (only mRNA moves out of the cytoplasm; tRNA and mRNA in cytoplasm
nitrogen bases of DNA A-T, G-C
nitrogen bases of RNA A-U, G-C
sugar in DNA is deoxyribose
sugar in RNA is ribose
shape of DNA double helix (helical/ spiral)
shape of RNA straight; loop
functions of DNA stores info about cell and for protein synthesis, contains genetic instruction used in development and functioning organs, involved in trancription
functions of RNA carries info from DNA (codon) to the ribosome in the cytoplasm for protein synthesis; carries amino acid, involved in transcription (mRNA), an translation(mRNA, tRNA, rRNA), have codon (mRNA), and anticodon (tRNA)
Catabolic breaking down ex: digestion
Anabolic building up ex: photosynthesis
whats a codon 3 nitrogen bases
structure of mRNA straight; single chain
structure of tRNA single chain with loop like clover shape
location of mRNA nucleus, moves into the cytoplasm
location of tRNA in cytoplasm
special functions of mRNA carries the codon, codon- 3 nucleotide sequence complementary to DNA strand being trancribed, involved in protein stynthesis (trascription and translation)
special functions of tRNA carries the amino acid and the anticodon, anticodon- 3 nucleotide sequence complementary to mRNA, involved in protein synthesis and translation

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.
