The video describes the process of DNA replication and the role of helicase in separating double-stranded DNA into single-stranded DNA. It introduces the technique of helicase-dependent amplification (HDA), a method used for amplifying DNA in the lab without requiring thermal cycling. HDA is an isothermal amplification method that occurs at a constant temperature and uses helicase to denature double-stranded DNA and facilitate nucleic acid amplification. The process of HDA involves the use of helicase to separate double-stranded DNA into single-stranded DNA, followed by the attachment of primers and the use of DNA polymerases to create new double-stranded DNA. HDA is a fast and easy method to amplify DNA and is useful for diagnostic purposes, particularly in remote areas where laboratory facilities are not readily available.
