When does DNA replication occurs?
DNA replication occurs during the synthesis (S phase) phase of interphase in the cell cycle.DNA replication begins in areas of DNA molecules called origins of replication.
DNA is copied during a process called?
Replication.
What separates the DNA strands during replication?
That would be called the Replication Fork
How are DNA replication and transcription similar?
RNA molecules produced by transcription are much shorter in length than DNA molecules produced by replication. Also in DNA replication the compliment of Adenine is Thymine. In transcription the compliment of Adenine is Uracil.
Is DNA replicated during G1?
Yes. Cell division refers to mitosis or meiosis.DNA replication occurs before every division for mitosis.In meiosis there are 2 separate cell divisions, and the DNA only replicates before the first one.
What is the helicase enzyme?
Unwinds the DNA during DNA replication and Trancription
What type of molecules are bonded together by hydrogen bonds in DNA?
Nitrogenous bases are held together by hydrogen bonds, thus making them easier to separate during DNA replication.
What happens During replication DNA .?
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.
When does DNA replication occurs?
DNA replication occurs during the synthesis (S phase) phase of interphase in the cell cycle.DNA replication begins in areas of DNA molecules called origins of replication.
What is the function of these short RNA segments during replication?
they form mrna molecules used in translation
During what kind of processes are atoms and molecules rearranged?
a chemical reaction
What chemical force must be overcome in order to separate the two DNA strands during replication?
h bond
What is copies during replication?
A cell's DNA is copied during replication.
DNA is copied during a process called?
Replication.
What separates the DNA strands during replication?
That would be called the Replication Fork
Does any transpiration occur during photosynthesis?
They are separate processes. So it can be occured
It is necessary for DNA strands to be held together with relatively weak hydrogen bonds?
so that the DNA strands can separate easily during replication.
