QuestionAnswer
what are the requirement of DNA replicaiton initationextensionUnzipping/ UnwindingproofreadingTermination
What is origins of replication where DNA duplication begins.
What is the replicaiton of DNA semiconservative
what is prokaryotes and eukaryotes prokaryotes have one origins of replication whereas eukaryotes have many
what is the difference between unidirectional replication and bidirectional replicaiton? Unidirectional replicaiton require only one replication whereas bidirectional replicaiton require two replicaiton fork
what proteins are participate in DNA replicaiton? helicasesingle-stranded DNA biding proteins (SSB proteins)gyraseRNA primerDNA ligaseDNA polymerase IIIDNA polymerase I
what is the leading strand replicaiton one strand is continuously synthesized in the normal 5'- 3' direction
Why is the proofreading so important? Because it has a function to correct the mistake when the DNA polymerase adds the wrong nucleotide
what it the function of RNA primase initiates new strand synthesis
what is the function of gyrase cleaves and swivels duplex to release mechanical stress of unwinding
what is the function of DNA ligase joins okazali fragments on lagging strand
what is th function of helicase unwinds DNA at the replication fork
what is the function of SSB proteins bind and stabilize single-stranded DNA at replicaiton fork.
what is complementary sequences? a nucleic acid sequence of bases that can form a double-stranded structured by matching base pairs.(G-T-A-C)
what is phosphodiester linkage a bond between the 3' carbon of on sugar to the 5' phosphate of the adjacent sugar
chargaff's rule states that the ratios of purines to pyrimidines and also o adenine to thymine and of guanine to cytosine were close to one
conservative replication both parent strands would remain together, and two new synthesis strands would form a second double helix
semiconservative replicaiton hydrogen bonds between the two stands break, two strands separated and each trand pair with the nw complementary nucleotide to replace the missing partner.

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.
