What Is DNA Replication

When talking about genetics, the term ‘DNA replication’ usually comes out. While people are very interested in the subject, most of them do not even know what DNA is, let alone what is DNA replication. They know that DNA is very important and that it has a major part in the developing and functioning of all living organisms, but they do not know what is DNA exactly. So before talking about DNA replication, we should start by settling once and for all what is DNA. Well, DNA stands for deoxyribonucleic acid, which is a nucleic acid containing all our genetic information. The DNA is made out of structures called genes, but there are also other DNA sequences, which serve various purposes.

Basically, DNA is an essential macromolecule for all the known forms of life. Now that you know what DNA is, we should move on to what is DNA replication. DNA replication is a very complex process, which occurs in all living organisms, as all known forms of life have a DNA. This biological process copies the DNA of the previously mentioned living organisms, so this is how the genetic information is being transmitted from parents to children. DNA replication begins with one double-stranded DNA molecule, and it produces two identical copies of that molecule. In plain English, the genetic information contained by both of the strands combines, and merges into a simple unit. You can see. Thus, that DNA replication is the reason why children inherit features from both parents, because their DNA contains genes from both of them.

However, DNA replication occurs on lower scales too, because this process is vital for cells to multiply, as well. This process occurs even in the prokaryote cells. DNA replication begins in the genome, at specific locations called ‘origins’. However, due to the latest developments in technology, DNA replication can also be performed artificially, ‘in vitro’, but only in special laboratories. Nevertheless, now that you know what is DNA, and also what is DNA replication, I am sure that you better understand the complex process of how life is created.
