1
New cards

Helicase

It breaks the hydrogen bonds between the base pairs, Separating the two DNA strands, turning the double helix into two single strands so they can be copied. Creating Y-shaped structure called the replication fork where new DNA will be built

2
New cards

Single-Stranded Binding Proteins (SSBPs)

They stick to the single strands and hold them apart, so the hydrogen bonds don’t reform. If the strands came back together, replication couldn’t happen.

3
New cards

Topoisomerase

It moves ahead of helicase and makes small cuts in the sugar-phosphate backbone of the DNA. This relieves tension and prevents supercoiling or tangling as the DNA unwinds.
