WebHelicases are "motorized" proteins that help unwind DNA by separating duplexed DNA into single-stranded form. They are powered by the energy derived from ATP hydrolysis. Helicases have a polarity that is defined as the direction they travel along single-stranded DNA (i.e., either in a 5'→→ 3' or in a 3'→→ 5' direction). WebNone of the answers are correct A 3. DNA helicase enzymes move in what direction along the DNA during DNA replication? A. 5' to 3' B. 3' to 5' C. They remain stationary A 4. Manufactures a 10-12 base segment of RNA. A. DNA ligase B.

WebAug 24, 2024 · Helicases move along one strand of the duplex and push the opposing strand aside. They either migrate in the 3'-5' or 5'-3' orientation along the DNA or RNA (some can move in either direction). Living things need helicases, which are enzymes, to separate the double-stranded DNA in this instance from other nucleic acid strands.
