DNA replication BF

QuestionAnswer
What is the structure of DNA? Double helix
How are mutations spread? Parent cells give mutations to daughter cells
What is DNA polymerase? A hereditary disorder characterized by familial multiple tumors and caused by a mutation in the p53 gene
Replication the duplication of DNA
Helicase splits 2 strands of DNA by splitting hydrogen bonds
Single stranded binding proteins binds to outside of single strands to keep strong and safe and to keep strands apart
Primerase makes RNA primer
RNA Primer gives polymerase a way to attatch and gives 3 prime end to attatch to the 5 prime end; gives stability
5 prime end of nucleotide how one nucleotide connects to the next
3 prime end of nucleotide how one nucleotide connects to the next
Orgin of replication site where replication bubble begins
Replication bubble splits DNA from replication from orgin of replication
Replication fork part of replication bubble that has not split yet
Leading strand new strand that grows towards the replication fork
Lagging strand new strand that grows away from replication fork
Ligase joins Okazaki fragments
Telomere ends of chromosomes
Telomerease an enzyme that adds DNA sequence repeats
Transcription transcribes DNA into RNA, creats an RNA strand complimentary to the DNA
Promoter specific sequence that is similar in all genes
RNA Polymerase binds to promoter, stops moving when reached TAC
Start Triplet TAC when RNA polymerase starts making RNA, on the DNA strand
Start Codon AUG when RNA polymerase starts making RNA, on the RNA strand
5 prime cap made of guanine, on start end of RNA
3 prime Poly A tail made of adenine, it's on stop end of RNA

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.
