what it DNA Replication

All living organisms have a process within them called DNA Replication. What is DNA Replication, you ask? It is an important process by which the root identity of an organism copies itself, or makes more of itself.

DNA, or deoxyribonucleic acid, is the genetic sequence or code that makes each living organism unique on the molecular level. DNA Replication involves this microscopic sequence or code creating more of itself. A single strand of DNA molecules undergoes DNA Replication and the result is another identical strand.

DNA Replication usually occurs within cells. There is a specific area within the cell, called a genome, in which this fundamental process occurs. The DNA strands unravel and rearrange themselves at the genome. The synthesis of these strands and proteins is how the DNA within cells begins to extend and ultimately reproduce itself.

The process of DNA Replication can also occur on the outside of a cell, which is called 'in vitro.' The synthesis that would occur within a cell has to be initiated artificially using what is called DNA primers. The process of polymerase allows the DNA primer to locate and copy a specific strand within a pool of DNA molecules. This is a common lab procedure.

When DNA is replicated, the double stranded structure or the DNA, which is coiled together, is separated. During this separation, each side of the strand is recreated individually. The new strands turn out to be identical, and the chance that there is any error is incredibly small.

DNA is one of the major building blocks of life. It is so tiny, yet it is important to all living things. It is a rather complicated process at first glance, however, it is easy to understand the need for DNA Replication.

This naturally occurring process is crucial to the survival of life on earth as we know it. The reproduction of all life depends on the ability of DNA to make copies of itself. For example, when a woman become pregnant, proper DNA replication has to occur, otherwise the baby will not survive or there will be deformities. Babies start off as a cell, and the cell divides. Before the cell divides, in order for the baby to properly develop, the DNA must replicate itself accurately. In the rare case that the development does not occur properly, there will be something missing in the baby's genetic code.

The same is true in animals, and bacteria. DNA replication occurs all around us everyday. In both humans and animals, and basically all living things, our dna is constantly making more of itself. When you get a wound, your body will grow new skin. DNA is constantly working to rebuild itself again and again.

Studies of artificial DNA Replication are ongoing to help individuals have children, regrow skin, and hair. Artificial organs and limbs are being worked on as well. The ability of cells to reproduce is vital to the survival of our world, and the more we learn about it, the better off we will be.
