What unzips DNA so it can duplicate?
Helicase enzymes
Why does a cell need to replicate its DNA quickly?
In human cells about 50 nucleotides are added every second to a new strand of DNA at that rate it would take days to to replicate a molecule of DNA. So it replicates all along the chromosome so it only takes a few hours.
What is the function of DNA helicare in DNA replication?
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
Does a molecule have DNA?
DNA is a molecule so no.
Why can't red blood cells reproduce?
They have no Nucleolus so Therefor there's no DNA to Replicate.
Replication explain how the structure of DNA allows it to be duplicated so easily why cant protein be copied so easily?
Replication begins when an enzyme called DNA helicase attaches to a DNA molecule, moves along the molecule, and "unzips" the two strands of DNA.

Is it true mitochondria are able to replicate themselves?
Yes they have own DNA. So they replicate by their own
What is the importance of DNA transcrip?
DNA transcrip transcribes the DNA so that RNA may use it and replicate it.
Why do nitrogenous bases break apart during DNA replication?
So that the DNA can replicate/duplicate.
How are chloroplast produce?
They got their own DNA. So they replicate themselves
When DNA unwinds unzips and pairs up to form 2 identical strands of DNA?
This occurs during the process of DNA replication
Where do the 2 strands of the parent DNA end up in the daughter chromosome after DNA replication?
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.
