More DNA. The DNA unzips and then makes more from the code that genes give, It has to fit A with T and C with G. Mutations happen when the DNA does not unzip on time and the new DNA still sticks to the DNA that was supposed to unzip

What are two ways that the end result of transcription and replication of DNA differ?
In the replication part, replication ensures that each new cell will have one complete set of genetic instructions. it does this by making identical strands of chromosomes. transcription enables to adjust to changing demands. it changes certain types of strands on the DNA
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.
What is the DNA Replication?
DNA replication is the process in which the hydrogen bonds between the two strands of DNA are broken and then new DNA nucleotides are bonded along each strand according to the base-pairing rule. The result is two identical molecules of DNA.
What is it called when DNA separate into two strands?
DNA Replication by enzymes that copy DNA for chromosomes in the new cell after cell division (mitosis)
What is the process by which a DNA molecule is copied called?
dna replication. can be summarised as the two helical strands of dna unravelling through the action of enzymes and the corresponding nitrogenous bases of each being matched up (A-T, C-G) to form two identical strands
Difference between sister chromatids and homologous chromosomes?
Homologous chromosomes are individual chromosomes inherited from each parent. Sister chromatids are the result of DNA replication, and the are identical.

Why are Chromosomes called Double Chromosomes?
After DNA replication, there are double the number of chromosomes, which will be divided into two identical daughter nuclei during mitosis. For example, a normal human body cell has 46 chromosomes. When it undergoes DNA replication, the chromosomes are doubled so that there will be 92 chromosomes, consisting of 46 pairs of sister chromatids. During mitosis, the sister chromatids separate into two identical daughter nuclei, each having 46 chromosomes.

After replication 2 identical molecules of?
After replication two identical molecules of DNA are created.
The chromosomes are copied?
DNA makes up with chromosomes. The DNA is copied during DNA replication.

DNA replication results in two identical DNA molecules. What role do DNA helicases have in DNA replication?
DNA helicases break the hydrogen bonds in the DNA molecule
Human chromosomes have hundreds of where the dna is unzipped so replication can begin?
origins of replication
Do the two DNA double helics following DNA replication have the same or different composition?
They should be identical to the original DNA that underwent replication.
Do the two DNA double helics following DNA replication have the same or a different composition?
They should be identical to the original DNA that underwent replication.
Why is DNA copied in the process of replication?
DNA replication occurs because there need to be two identical copies of DNA before the nucleus of the cell divides, so that each new nucleus has a complete and identical copy of DNA.
