QuestionAnswer
RNA ribonucleic acid
mRNA messenger RNA; carries instructions
rRNA ribosomal RNA; assembles proteins in ribosomes
tRNA transfer RNA; carries amino acids to the ribosomes to match them with the right mRNA coded sequence
transcription making RNA
RNA polymerase RNA enzyme piece
promoter a section with a specific code to start
polypeptide long chains of amino acids
genetic code A = U, C = G
codon mRNA 3-letter code to make proteins
start codon the first 3-letter protein code
stop codon the last 3-letter protein code
translation ribosomes use the sequence of codons to assemble amino acids into polypeptide chains
anticodon tRNA 3-letter code that complements the mRNA code
gene expression the end result; all these codes that have been copied gets put together to form new DNA that determines your traits
proteins long chains
RNA translation protein synthesis
substitution wrong nitrogen base added when a protein is made

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.
