SLS Bio12 DNA RG

SLS Bio12 DNA Protein Synthesis RG

complementary base pairing H- Bonds between bases. A with T, : two hydrogen bonds. G with C: three hydrogen bonds
DNA helicase Unwinds and unzip the double stranded DNA
DNA polymerase Positions and joins nucleotides for complementary base pairing
recombinant DNA
replication Copying one DNA helix into two identical helices
semi-conservative replication Each new double helix has one old conserved strand and one new strand.
anti-codon Triplet set bases that is complementary to a specific codon of mRNA
codon each 3-nucleotide unit of a mRNA molecule
DNA sequence (genetic code genetic information as a species
Elongation Amino acids are added one at at time to the growing polypeptide
environmental mutagen Radiation, organic chemicals. Causes errors in replications that faults protein syntheses with a faulty protein produced.
genetic disorder
initiation First tRNA has come to the robosime and attached to the mRNA with the anticodon pertaining to the codon on the mRNA
messenger RNA (mRNA) Takes a message from DNA to the ribosomes. In cells, DNA is in the nucleus, and the ribosomes are in the cytoplasm
mutation the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA
Termination Ribosomes separated into its two subunits, and the polypeptide is released
transcription a Segment if DNA serves as a templte for the production of mRNA. RNA polymerase builds the mRNA sequence from the promoter DNA template
transfer RNA (tRNA) Bring amino acids to the ribosomes. One end is a specific nucleotide sequence with a specific amino acid. Other end is anticodon.
translation Gene expression leads to prtein syntheses. Requires several enzymes. mRNA, tRNA, and rRNA

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.
