DNA (deoxyribosenucleic acid) replicates by a process called semi-conservative replication. In semi-conservative replication, one side of the DNA structure as acts a template and guide for the other strand to copy. Floating nucleotides then match up with the corresponding base (adenine base pairs with thymine, and cytosine base pairs with guanine). This pairing system is known as complementary base pairing.
The fact that one side is copied exactly like the other, and the bases are always joined in the same sequence means the chances of a mutation is lessened, hence the two copies are exactly like the original DNA.
What else can I help you with?
How do the new copies of DNA compare to the original DNA?
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.
When DNA splits a new 'what' of DNA is formed?
When DNA splits, two new strands of DNA are formed through a process called DNA replication. Each new strand is complementary to the original strand, resulting in two identical copies of the DNA molecule.
Why do new copies of DNA have to be similar to the original strand?
New copies of DNA have to be identical to the original strand so that the cells can function properly. If mistakes are made in DNA replication, it could cause a mutation to occur. In body cells, that means the possibility of tumors, including cancer. In gametes (sperm and egg cells), this could mean are very harmful genetic disorder, or it could be so bad that the organism produced by fertilization may not be able to survive.
How does DNA semi-conservative replication help prevent mutations in DNA replication?
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.
What is the role of the DNA new strand?
It is a copy of the Dna original strand.
How do the new copies of DNA compare to the original DNA?
DNA replicates using the process called semiconservative replication. An original DNA molecule is complementary to the replicated molecule, which means that they are identical copies of each other.

When DNA splits, two new strands of DNA are formed through a process called DNA replication. Each new strand is complementary to the original strand, resulting in two identical copies of the DNA molecule.
If you compare the original DNA to the two copies that are made after replication occurs what would you find?
Unless mutation occur the two copies of DNA that are made after replication are identical to its original form. Thus continuous replication of DNA in the chromosomes does not alter its nature.
Process when DNA copies itself?
DNA replication is a semi-conservative process where the double-stranded DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. DNA polymerase enzymes read the template strands and add nucleotides to form the new strands, resulting in two identical copies of the original DNA molecule.
Why do new copies of DNA have to be similar to the original strand?
New copies of DNA have to be identical to the original strand so that the cells can function properly. If mistakes are made in DNA replication, it could cause a mutation to occur.

DNA undergoes a process called when it is duplicated?
DNA replication
The replication of DNA molecules results in four copies of the same gene?
During DNA replication, a double-stranded DNA molecule is unwound and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical DNA molecules, each containing one original strand and one newly synthesized strand. So, the result of DNA replication is two identical copies of the original DNA molecule, not four copies of the same gene.
What copying process by which a cell duplicates its DNA is?
Replication!!
How is anything genetically modified?
Scientists have the means to extract the DNA strand from a cell. Once the DNA strand is removed, it can be altered, then placed back into the cell. When the cell divides and multiplies - the new copies will retail the altered DNA rather than having the original.
How does DNA semi-conservative replication help prevent mutations in DNA replication?
Semi conservative replication prevents mutations during DNA replication because it produces 2 copies that each contained 1 of the original strands and 1 entirely new strand.
Why is DNA replication considered semiconservative?
DNA replication is semiconservative because each new double helix contains (1) old and (1) new strand. each mother strand serves as a template for a new strand.The two strands are complementary, but not identical.
What happens at a DNA replication for during replication?
The hydrogen bonds that hold the two DNA strands together are broken. This creates two prongs and each are made up of a single strand of DNA that creates two new partners for the two strands (because they add nucleotides).
