Gene Expression: DNA>RNA>Protein

QuestionAnswer
Gene Expression DNA is the instruction blueprint in code; RNA is the usable copy that transports the recipe to the protein factories and carries in the ingredients needed for the ribosome to assemble various proteins
nucleotide bases in RNA adenine, cytosine, guanine, uracil
Codon set of three nucleotides-- help text the DNA message to the ribosome
RNA ribonucleic acid, containing ribose sugars
mRNA 'message' that is a recipe for making proteins from amino acids.
RNA nucleotides adenine(A) pairs with uracil (U) rather than thymine (T); cytosine(C) still pairs with guanine(G)
RNA polymerase molecule that attaches to DNA- builds different types of RNA.
tRNA "transport" RNA - in the cytoplasm- carry amino acids to ribosomes.
rRNA "ribosomal" RNA is the structure of the protein factory
3 Types of RNA rRNA or ribosomal RNA, tRNA or transfer RNA and mRNA or messenger RNA.
ribosomes sites where amino acids are linked to one another to create peptide chains called *proteins*.
transcription process: matches nucleotide sequence from a gene to form a complementary message strand of RNA
translation process: reading codons on mRNA; calls for tRNA carrying amino acids; amino acids are linked into polypeptide chains that will form a protein.
anticodon 3 nucleotide sequence on each tRNA that carries the exact base pairs for the codon on mRNA

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.
