E. coli, like all prokaryotes, replicates by an asexual process called binary fission. When a cell goes through binary fission, it must first make copies of everything that the cell needs to survive--proteins, inclusions, ATP, and DNA. The cell makes a copy of it's own DNA through a process called replication, and then binary fission occurs, and one cell splits into two new cells with identical DNA. E. coli is capable of performing this process every 20 minutes, as long as there is sufficient nutrients available to it.
To pass on heredetary information to next generation.
The same reason anything has DNA- to pass on information to the next generation. DNA is also what controls the cell's activities. It's the instruction manual that makes a pea what it is.
The study of how traits pass from one generation to the next is called genetics. Genetics involves the analysis of DNA, genes, and chromosomes to understand inheritance patterns and variations in organisms.
It passes information by way of genes which are found in our DNA. We use reproduction to do this.
Genetics Genes are the DNA that pass our hereditary traits from generation to generation
DNA
The DNA replicates with the mutation on it, spreading it
The polymer used to pass hereditary material is DNA (deoxyribonucleic acid). It contains the genetic instructions that determine the development and functioning of living organisms. DNA is located in the cell nucleus and is responsible for transmitting genetic information from one generation to the next.
Mutations not only change the DNA, but a change to the DNA will change the mRNA. This explains why a mutation in one generation can be passed on to the next generation.
EUKARYOTES The chemical information for making proteins is carried in the DNA, which is found on the chromosomes in the cell nucleus. Whan a eukaryotic organism undergoes asexual or sexual reproduction, the DNA is replicated, and the DNA of the parent organism(s) is passed on to its/their offspring (the next generation). PROKARYOTES The single circular chromosome undergoes DNA replication, which creates two identical chromsomes. The new chromosome is passed to the next generation by a process called binary fission.
DNA, undergoes through replication that transmits genetic information.
