503 DNA Replication

honors

TermDefinition
Replicate - to copy
Semi- - partially
semi-conservative - in each new DNA double helix, one strand is from the original molecule, and one strand is new
free nucleotides - nucleotides that have not yet been joined together to form a DNA or RNA strand
parent molecule - In DNA replication, the DNA strand that is going to be copied
daughter molecules - In DNA replication, the two new molecules They are identical to each other and the parent molecule They are not male or female
Template strand - The DNA strands that have been unzipped from each other during DNA replication They serve as "templates" for the new strands
Primer - An RNA molecule It tells DNA polymerase where to begin replication
Four of the enzymes involved in DNA replication - DNA helicase, primase, DNA polymerase, and DNA ligase
primase - An enzyme Adds a primer to the DNA strand The primer tells DNA polymerase where to start
DNA helicase - An enzyme It unwinds the DNA during replication
DNA polymerase - An enzyme It creates the new strands of DNA during replication It does this by pairing free nucleotides to the template strand
DNA ligase - An enzyme It connects the sugar-phosphate backbones of new strands of DNA to each other
direction of DNA replication - DNA polymerase always begins replicating at the 3' end of the template DNA strand It moves from the 3' end toward the 5' end
Leading strand - The new strand that is created continuously within the replication bubble
The lagging strand - The new strand that is created in fragments, or small sections, within the replication bubble
Replication "bubble" - DNA replication takes place in many location simultaneously During replication, the sites of replication look like "bubbles" in the DNA molecules
Exonuclease - An enzymes that removes the primers

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.
