Why is DNA replication essential? | It is necessary for the creation of new cells so they may create more cells in the future. |
What type of cell carries the DNA in its nucleus? | Eukaryotes Cell |
What type of cell carries the DNA in its body? | Prokaryotes Cells |
When does the DNA get replicated? | During Interphase |
What are the key enzymes in the replication of DNA? | DNA Polymerase, Helicase, Primase and Ligase |
What is the role of Helicase? | To "unzip" the DNA and break the Hydrogen bond. |
What is the rold of DNA Polymerase? | To replicate the DNA molecules and build a new strand. |
What is the role of Primase? | To create a primer for the DNA Polymerase to know where to begin/end. |
What is the role of Ligase? | To fill any gaps on the "Lagging strand" so that the DNA strand is complete. |
What do SSB proteins do? | Bind the DNA strands to maintain their separation during the replication process. |
What direction can DNA Polymerase travel? | Only from 5' prime to 3'prime direction. |
What is the leading strand and lagging strand? | There is one strand in which DNA Polymerase can replicate faster, that is called the "leading strand", the other is called the "lagging strand" because it is slower. |
What is an Okazaki fragment? | They are the fragments left on the lagging strand from DNA polymerase starting and ending in fragments. Ligase has to fill them with a glue to complete the strand. |
