Answer: Osmosis is the movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration, tending to equalise the concentrations of the solutes. Osmosis is passive transport, meaning it does not require energy to be applied.
Examples of osmosis in daily life include plant cells soaking up water, skin soaking up water, and slugs reacting to salt.
The function of Helicase in the process of DNA replication is to untwist the double helix and separating the two DNA strands. This action of helicase creates the replication forks and replication bubbles where the process of replication is initiated. Their main role is the separation of double-stranded DNA into single strands allowing each strand to be copied during the process of replication. It may also function in other cellular processes where the double-stranded DNA must be separated, including transcription and repair. <span />
