In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNAmolecule. This process occurs in all living organisms and is the basis for biological inheritance. The cell possesses the distinctive property of division, which makes replication of DNA essential.
DNA is made up of a double helix of two complementary strands. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.[1][2]
In a cell, DNA replication begins at specific locations, or origins of replication, in the genome.[3] Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bi-directionally from the origin. A number of proteins are associated with the replication fork to help in the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand. DNA replication occurs during the S-stage of interphase.
DNA replication can also be performed in vitro(artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule. The polymerase chain reaction(PCR), a common laboratory technique, cyclically applies such artificial synthesis to amplify a specific target DNA fragment from a pool of DNA.

hm... same to you
gud morng
yeah good morning
kk dont chat here
ok
then where
ok bye
u wanna chat
then chat in message not here

DNA replication is a biological process that occurs in all living organisms and copies their DNA; it is the basis for biological inheritance.
If DNA wasn't copied before cell reproduction, after the cells divide they would only have half the DNA that the original cell had.
And since we need all our DNA to tell the rest of the cell how to carry out all functions, with only half the DNA, a cell would shut down.Placenta is located between the developing foetus and the uterine walls
