What is DNA replication with diagram?
The first step of DNA replication is the unwinding parent double helix molecule so that each strand acts as a template for the new strand. Unwinding mechanism is very complex. Hydrogen bonds between two strands are broken. This is achieved by enzymes called DNA helicases which move along DNA and separate the strands.
What are the 5 steps of DNA replication?
What are the 5 steps of DNA replication in order?
- Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.
- Step 2: Primer Binding. The leading strand is the simplest to replicate.
- Step 3: Elongation.
- Step 4: Termination.
What are the 10 steps of DNA replication?
Terms in this set (10)
- DNA unwinds @ origin of replication.
- helicase opens up DNA and makes replication fork.
- single strand bonding proteins coat DNA around replication fork to prevent rewinding DNA.
- topoisomerase binds @ region ahead of replication fork to prevent supercoiling.
What is the first step in the process of DNA replication?
The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).
What are the 6 steps of DNA replication?
The complete process of DNA Replication involves the following steps:
- Recognition of initiation point.
- Unwinding of DNA –
- Template DNA –
- RNA Primer –
- Chain Elongation –
- Replication forks –
- Proof reading –
- Removal of RNA primer and completion of DNA strand –

Key Points
- Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release.
- During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
What is DNA replication and its process?
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Which initiates the process of replication?
A primer provides the free 3′-OH end to start replication. DNA polymerase then extends this RNA primer, adding nucleotides one by one that are complementary to the template strand.
