DNA replication is an essential step in cell growth. Cell growth is what drives the growth of an organism.
Every time a cell divides, the DNA in the cell has to be be replicated (an extra copy has to made to go into the newly formed cell)
Therefore, DNA must be able to self replicate so that cells can divide and organism can grow and develop.
DNA replication is also essential when extra cells are required in a adult organism. When there is a wound or injury that results in a loss of cells, more cell have to be grown by the body in order to replace the lost cells. In such a case, cells have to divide and there has to be a copy of the DNA for each new cell
In a word: complementarity.
The DNA molecule consists of two antiparellel strands of nucleotides linked by pairing between the nitrogenous bases A, C, G, and T. Where there is an A in one strand, there must be a T in the other strand, where there is a C in one strand there must be a G. And so on. Because of this property of complementarity (as in each strand complements the others) a single DNA strand can be used to generate the other.
When DNA is replicated the two strands are broken apart and two new strands are synthesized, complementary to the two old strands. DNA can be replicated because the two halves of an old molecule can be used as templates to generate two new halves to create two new molecules.
Picky Aside:
It is not accurate to say DNA replicates itself. DNA is replicated by a massive array of protein co-factors and enzymes. DNA is a replicable molecule, not a replicating molecule.
DNA must replicate itself before mitotic cell division so that the two new daughter cells have the same amount of DNA, and identical DNA.
A characteristic of a DNA molecule that is not characteristic of a protein molecule is that the DNA molecule can replicate itself.
DNA
Enzymes unwind the DNA molecule into two strands.
the dna must replicate itself in order to make two exact copies:D
See reconstruction means DNA repair rather than replication. Certain polymerases(DNA Pol-1) exibits 3'-5' exonuclease activity by which a mismatched or wrong nucleotide sequence is replaced by accurate one and sealed by DNA ligase enzyme.this is called sealing often involved in reconstruction.

DNA
through replication
Yes.
true
Yes
Enzymes
Every guanine has to pair with cytosine and every adenine has to pair with a thymine. If this wasn't a rule then DNA can't replicate itself and mutations would occur.
Meiosis
During the S - [Synthesis] phase of Interphase.
No conjugation is just the formation of conjucation tube for the transfer of replicating DNA molecule
it has to have the same features
