TermDefinition
Ribonucleic acid a natural polymer that is present in all living cells and that plays a role in protein synthesis
transcription the process of forming a nucleic acid by using another molecule as a template; particularly the process of synthesizing RNA by using one strand of a DNA molecule as a template
translation the portion of protein synthesis that takes place at ribosomes and that uses the codons in mRNA molecules to specify the sequence of amino acids in polupeptide chains
protein synthesis the formation of proteins by using info contained in DNA and carried by mRNA
ribose a five carbon sugar present in RNA
messenger RNA a single stranded RNA molecule that encodes the info to make a protein
ribosomal RNA an organelle that contains most of the RNA in the cell that is responsible for ribosome function
transfer RNA an RNA molecule that transfers amino acids to the growing end of a polypeptide chain during translation
RNA polymerase an enzyme that starts the formation of RNA by using of strand of a DNA molecule as a template
promoter a nucleotide sequence on a DNA molecule to which an RNA polymerase molecule binds, which initiates the transcription of a specific gene
termination signal a specific sequence of nucleotides that marks the end of a gene
genetic code the rule that describes how a sequence of nucleotides, read in groups of three consecutive nucleotides (triplets) that correspond to specific amino acids, specifies the amino acid sequence of a protein
codon in DNA a three nucleotide sequence that encodes an amino acid or signifies a start signal or a stop signal
anticodon a region of tRNA that consists of three bases complimentary to the codon of mRNA
genome the complete genetic material contained in an individual

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.
