QuestionAnswer
The three possible models of replication were ___Conservative____, semi-conservative, and dispersive.
Meselson & Stahl determined that replication was __Semi-conservative____.
___Helicase____ does what? unwinds and separates the DNA.
__Topoisomerase____ does what? relieves supercoiling.
What stranded binding protein coat the single stranded DNA to protect it from degradation? Single
___Primers____ are small pieces of RNA to provide a 3’ hydroxyl group for DNA polymerase to add a nucleotide and are provided by the enzyme primase.
DNA ____Polymerase____ is the enzyme that adds the nucleotides to the newly growing DNA strand.
___Replication_____ takes place in the 5’ to 3’direction.
___Telomeres____ are the ends of the chromosome which track how many times a cell has replicated.
According to the video the leading strand replicates in a... __Continuous__ manner, while the lagging strand replicates in short pieces called Okazaki fragments.
What does Exonuclease do? removes the RNA ___Primer__ from the new DNA strands.
What does DNA ___Ligase__ do? joins all of the pieces of DNA in the new strands together by covalently bonding the sugar phosphate backbone.
What is telomerase? an enzyme that can maintain the ends of the chromosomes and is activated in cancer.
Prokaryotes have a __Circular____ chromosome.
In prokaryotes, DNA molecules are located in the Nucleus
In eukaryotes, nearly all the DNA is found in the Nucleus
The diagram below shows the process of DNA replication
The main enzyme involved in linking individual nucleotides into DNA molecules is DNA polymerase
During replication, which sequence of nucleotides would bond with the DNA sequence TATGA? ATACT
In eukaryotic chromosomes, DNA is tightly coiled around proteins called histones
When prokaryotic cells copy their DNA, replication begins at one point on the DNA molecule

Compared to eukaryotic cells, prokaryotic cells contain about one thousandth as much DNA.
How many cells are present after 80 minutes? 16
If the DNA of this bacterium is 4 million base pairs in length, how many total molecules of A,T,C, and G are required for replication to be successful? 4 million

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.
