Dna Replication Process Simple

Prokaryotes replicate their dna in the cytoplasm. A dna strand is composed of a long backbone of sugar and phosphate units. The process is called replication in sense that each strand of ds dna serve as template for reproduction of complementary strand.

This would happen in the eukaryotic cell’s nucleus before the cell divides, whether by mitosis or meiosis.

Dna replication process simple. Dna replication is the process of duplicating the dna molecule. Therefore the main role of replication is to duplicate the base sequence of parent dna molecule. This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of dna together (a with t, c with g).

The human genome (genome means a complete set of genes present in the cell) has around 3 billion base pairs (nucleotide pairing, remember?). As a semiconservative process, a single molecule containing two strands of dna in double helix formation is separated, where each strand serves as a template for the new dna molecules. First step of dna replication.

There are some differences in the control of dna replication in prokaryotic and eukaryotic organisms. The dna copied accurately in the daughter cells. General feature of dna replication.

Dna replication in 7 easy steps. The unwounding of the two strands is the starting point. Replication occurs for growth and repair;

Recall that, for eukaryotes, replication occurs during the s phase of interphase. Each strand of the original dna molecule The three steps in the process of dna replication are initiation, elongation and termination.

The process of replication is fairly quick, occuring at 50 nucleotides per second in human dna, thanks to multiple polymerases that can synthesize at the same time. In response to the molecular cues received during cell division, these molecules initiate dna replication, and synthesize two new strands using the existing strands as templates. The process of dna replication is vital for cell growth, repair, and reproduction in organisms.
