The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
Also question is, what is DNA replication and where does it take place?
DNA replication occurs in the nucleus of eukaryotic cell. By definition, prokaryotic cells do not have nuclei. Therefore, DNA replication occurs in the cytoplasm of a prokaryotic cell.
What is DNA replication when does it take place and why does it happen?
Explanation: DNA replication needs to occur because existing cells divide to produce new cells. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions! Here is a video which uses an animated tutorial to explain the process of DNA replication.
What is replication and where does it take place?
during which phase of the cell cycle does DNA replication occur? in which organelles does DNA replication occur in animal cells? in which organelles does DNA replication occur in plant cells? why must DNA replication in the nucleus occur before adult stem cells divide?
