DNA Replication

What is DNA Replication? Why does this process occur?

DNA is the process in which chromosomal DNA is copied before Mitosis or Meiosis. Without DNA replication, new cells would only have half the DNA of their parents. Species then would not be able to survive, and they could not grow up to reproduce successfully.

DNA replication is the process it that DNA is copied before Mitosis or Meosis. Without DNA replication new cells would only recieve half of the genetic information of thier parents. Then the species would not be able to survive.

DNA is the process in which DNa is copied before Mitosis or Meosis. Without DNa replication new cellw would only receive half the genectic code. Species would die or not be able to reproduce.

DNA is a proccess in which chromosonal DNA is a copied before Mitosis or Meisosis. Without it new cells would only have half the DNA of their parents. Species wouldnt be able to surevive and they could not grow or reproduce.

DNA replication is the process of DNA in the chromosomes is copied. Before this process a cell has to divide by mitosis and meiosis. Without this process new cellls would have only half the DNa of their patients. The organisms wouldn't be able to survive or reproduce successfully. All organisms go through DNA replication of some sort.

DNA replecation is the proces when chromosomal DNA is copied before Mitosis and Meisosis. Without this replecation the new cell would not be able make up a full DNA strand. This would in turn would end up killing us and, we could not reproduce.

It is the process in which the chromosomal DNA os copied befor Mitosis or Meiosis. Beacause our cells would only half of the DNA of our parents and then our species would not be able to survive.

DNA replication is the process in which chromosomal DNA is copied before Mitosis and Meiosis. We need DNA replication so we can have all DNA of our parents instead of half. Species wouldnt be able to survive without DNA.

DNA replication is the process where the DNA in the chromosomes is copied. If we didn't have DNA replication than the new cells would only have half the DNA of their parents. This could cause some species not to survive or would not be able to reproduce successfully.

The DNA in the chromosomes is copied in a process called DNA replication. Without DNA replication, new cells would have only half the DNA of their parents. Species could not survive, and individuals could not grow or reproduce successfully. All organisms undergo DNA replication.

A cell can divide by mitosis or meiosis, it must first make a copy of its chromomes. The DNA in the chromomes is copied in a process called DNA replication Without DNA replication, new cells would have only half the DNA of their parents species could not survive, and individuals could not grow or reproduce successfully. All organisms undergo DNA replication

DNA replication is when chromosomal DNA is copied right before Mitosis and Meiosis. Every species goes through DNA replication because if they didn't they wouldn't be able to reproduce or survive.

DNA is the process in which the cell is devided by mitosis and meosis nd dna makes a copy of its chromosomes.without dna speices can't survive and individuals can;t grow or reproduce.

DNA being copied is DNA replication. new cells would only have half the dna of their parents. we would all die.

DNA is Replicated so the cell cen split with its own DNA. It is the reson you cen Leve DNA any ware. It occurs to make or replace the DNA

Gil said...

DNA replication is when a person or animals DNA is copied it is the same as before but it is new. it is like a clone but it is in the same person. and when new cells are moving in and old are going out some of the dna is going with it but it cant change it is just new.

A sperm cell and an egg cell of two fruit flies, both produced through meiosis, unite to form a fertilized egg. From one fertilized egg, a friut fly with millions of cells in produced by the process of mitosis. Each cell can has a copy of the DNA that was in the original fertilized egg.
