|
||||
| Leading Strand Replication | show 🗑
|
||||
| show | enzyme that replicates the leading strand.
It reads the template one base at a time incorporating complementary nucleotides, ligating their 5' phosphate to the 3' OH of the growing leading strand
🗑

| show | restores the DNA to the proper level of supercoiling
🗑
|
||||
| show | RNAse
DNA polymerase beta
DNA Ligase
🗑
|
||||
| show | This enzyme digests any RNA
🗑
|
||||
| show | This polymerase fills in gaps in DNA.
It fills in the gaps left after the RNA primers are removed.
Leaves nicks in teh DNA
🗑
|
||||
| show | Binds any free 3' hydroxyls and 5' phosphates of DNA.
It seals the nicks between the okazaki fragments left by the Pol beta.
🗑
|
||||
| show | Reverse transcriptase
Uses RNA as a template to make DNA
Fills in the gap from overhang that can't be filled in by the DNA polymerase.
It also extends the length of the DNA
🗑
