What direction does DNA replication occur?
|
5'---> 3' direction

|
|
In DNA replication, what does RNA primase do?
|
adds a short length of RNA which acts as a primer, allowing DNA polymerase to bing and begin replication
|
|
|
In DNA replication, what does DNA polymerase III do?

|
|
In DNA replication, what does Helicase do?
|
uncoils the DNA double helix and splits it into 2 template strands
|
|
|
In DNA replication, what does DNA polymerase I do?
|
removes the RNA primer and replaces it with DNA
|
|
|
what are Okazaki fragments?
|
short lengths of DNA between the RNA primers
|
|
|
In DNA replication, what is DNA ligase?
|
seals up the gaps between okazaki fragment by making sugar-phosphate bonds (covalent bonds)
|
|
|
How many phosphate groups do free nucleotides used for DNA replication have?
What are they called? |
They contain 3 phosphate groups. Two phosphates are removed during replication to release energy
Called deoxyribonucleoside triphosphate |
