Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.

Answer:
The correct answer is: semi-conservative.
Explanation:
DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.
DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.
DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).
DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
