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.

WebHelicase breaks the hydrogen bonds between the parental DNA strands and unwinds the double helix. Single-stranded binding proteins bind to the single strands of DNA, preventing them from reannealing and allowing synthesis to occur on both strands. WebWhen two strands of DNA associate to form a double helix, the bases on opposite strands of DNA interact via hydrogen bonds. Different numbers of hydrogen bonds form between the different base-pairs: there are ....... hydrogen bonds between adenine and ....... , and between cytosine and. ....... there are ....... hydrogen bonds. http://compbio.biosci.uq.edu.au/mediawiki/index.php/DnaB_Helicase#:~:text=Separation%20is%20carried%20out%20by%20molecular%20motors%20known,DNA%2C%20destabilizing%20the%20interactions%20between%20complementary%20base%20pairs. marithe girbaud francois
