Replicate DNA and you get DNA. Two from one.

After replication two identical molecules of DNA are created.


Each of the 2 DNA molecules made from DNA replication has an exact copy of the original DNA molecule


Two double stranded DNA molecules are created by the process of DNA replication.


DNA's structure comes in the form of a double helix. Replication is when the amino acid sequences within the DNA makes another copy of itself, resulting in 2 identical (ideally) molecules of DNA.


They should be identical, but mistakes can happen, possibly causing a mutation in one or both of the new DNA molecules.


1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.


During DNA replication the following occurs: 1) An enzyme called helicase separates the DNA strands (the space where they separate is called the replication fork). 2) DNA polymerase adds complementary nucleotides to the separated strand of DNA. 3) The DNA polymerase enzyme finishes adding nucleotides and there are two identical DNA molecules.


Each molecule ends up with one new strand and one original strand.


DNA undergoes DNA replication which involves the DNA strand unwinding and acting as a template for the next strand. The replication produces 2 additional strands that are made from the original DNA strand.


the third step in dna replication is when 2 dna double helix form together to form other dna double helix.


DNA replication is a process to create 2 new DNA molecules by splitting 1 DNA molecule. This occurs when a cell is about to divide and needs its own copy of DNA. The process consists of many different proteins and enzymes. This includes Gyrase, Helicase, Polymerase III, Primase (or RNA Polymerase), SSB's (or Single Stranded Binding Proteins), Ligase and Polymerase I. Each part has its own role for DNA replication to be successful.


When DNA replicates, the two strands become four strands, or two new bands of DNA. 2 of these strands are the originals, while 2 are completely new. That's why it's called semi-conservative. Replication "recycles" the DNA.


Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)



During DNA replication the two strands of the DNA helix split apart and the ribosome reads off the template strand producing an exact copy of this strand. Then RNA polymerase base pairs both of the strands, producing 2 semi-conservative strands.


Community Answer 1Cell Division_____________________________Community Answer 2During the process of DNA replication, DNA strands are copied (duplicated) to form new identical strands of DNA.



semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)


it look the opposite of the original strand.


To simplify: the DNA molecule unzips and divides into 2 strands, then the replication makes the complements of each strand to make 2 full DNA daughter chromosomes, so half the parent DNA ends up in each daughter chromosome.


This occurs during the process of 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.




Immediately after replication (S phase of a cell), the cell enters G2 phase and then the M phase (division of the cell). During division, specifically anaphase, the 2 pieces of DNA (chromatics) are separated from one another.
