DNA replication uses a semi-conservative method that results in a double-stranded DNA with one parental strand and a new daughter strand.

DNA replication generally occurs by a bidirectional mechanism in which two replication forks form at an origin and move in opposite directions, with both template strands being copied at each fork. Synthesis of eukaryotic DNA in vivo is regulated by controlling the activity of the MCM helicases that initiate DNA replication at multiple origins spaced along chromosomal DNA.

What do you know about this term DNA replication? If you have studied molecular biology, you might have some idea or even a deeper knowledge of this process. It's a process of a single DNA molecule producing its two replicas. Well, here in this quiz, we will ask you some questions related to this topic. Let's see if you can answer them or There are lots of origins of replication out there so, for simplicity’s sake, we've ignored those used in eukaryotic cells and viruses and focused only on those found in bacteria.

Replication biology

In molecular biology, DNA replication is the primary stage of inheritance. Central dogma explains how the DNA makes its own copies through DNA replication, which then codes for the RNA in transcription and further, RNA codes for the proteins by the translation. Replication forks are formed at each replication origin as the DNA unwinds. The opening of the double helix causes over-winding, or supercoiling, in the DNA ahead of the replication fork. These are resolved with the action of topoisomerases.

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). Other articles where Replication is discussed: heredity: DNA replication: The Watson-Crick model of the structure of DNA suggested at least three different ways that DNA might self-replicate. The experiments of Matthew Meselson and Franklin Stahl on the bacterium Escherichia coli in 1958 suggested that DNA replicates semiconservatively. Meselson and DNA replication generally occurs by a bidirectional mechanism in which two replication forks form at an origin and move in opposite directions, with both template strands being copied at each fork. Synthesis of eukaryotic DNA in vivo is regulated by controlling the activity of the MCM helicases that initiate DNA replication at multiple origins spaced along chromosomal DNA. Replication always starts at specific locations on the DNA, which are called origins of replication and are recognized by their sequence.

DNA replication is fundamental process occurring in all living organism to copy their DNA. The process is called replication in sense that each strand of ds DNA serve as template for reproduction of complementary strand.

DNA Replication - Steps. Enzyme breaks hydrogen between bases; DNA helix unwinds - two strands separate (unzip) Free nucleotides from the cytoplasm enter the nucleus, where they bond to complementary bases on the DNA strands. Result - two identical DNA molecules that are EXACT copies of the original. DNA Replication: Basic Concept Synthesis of
