Dna Replication

Dna replication is the biological process that happens to occur in all organisms and it copies thier DNA, it’s the basic process for biological inheritance. This process all begins when one double helix DNA molecule produces two exact identical copies of the molecule. Then the cell cycle begins, consisting of interphase, prophase, metaphase, anaphase and telophase. Each original strand of the double helix serves as an template for the production of the complementary strand. DNA replication begins at the “origin” which is located in the genome. DNA adds nucleotides matching to the template strand, a number of other proteins are associated with the initiation and the continuation of DNA synthesis.

Dna is mandatory for all living organisms, and organisms’ cells. Each new cell receives a copy of the genetic material from the cells’ parent(s). This process is called replication, the complete process of making the copy of the cells genetic material is quite complex. In humans, the genetic material is made up of molecules which are tightly packaged chromosomes. We have 23 pairs of chromosomes, each one contains one long DNA molecule and multiple protein molecules. DNA and protein molecules make up a figure which creates beadlike clusters. The DNA wraps around the clusters to form condensed and compact structure that we can only see when we were to look at an cell dividing under the microscope. Storage capacity of genes specifically resides in the DNA. Copying DNA is like trying to communicate through a message. The DNA molecule is the template of the message transfer.
Dna can be used as it’s own template, because the organization of the DNA is beyond specific. Two strands twist together in a spiral form, that exact concept of it earned the nickname, the double helix. DNA consists of small molecules, nucleotides. Another strand of nucleotides bonded together is nucleic acid, which adds onto DNA being an nucleic acid. Each of the nucleotides...
