DNA Replication in Eukaryotes: Linear Replication

DNA replication in eukaryotes is a complex and unique process involving many enzymes and thousands of ORI at a single time. Unlike the prokaryotic DNA, it involves a linear mode of replication. Why does linear DNA replication involve  multiple origins at a time? The large linear chromosomes in eukaryotic cell …

Replication in Circular DNA: Theta Model

Following Meselson and Stahl’s work, investigators confirmed that other organisms also use semiconservative replication. There are, however, several different ways that semiconservative replication can take place, differing principally in the nature of the template DNA—whether it is linear or circular—and in the number of replication forks. Replicon and Origin of …

The Discovery Of DNA Double Helix Structure : Watson & Crick’s Model

DNA or Deoxyribonucleic Acid is the hereditary material present in all living organisms through which genetic information of one generation is transferred to the next generation. Simply DNA is the structural & functional unit of heredity. DNA double helix is probably the most iconic of all biological molecules. Early Discovery  …

DNA: The Genetic Material

The cell nucleus plays a key role in inheritance was recognized in the 1870s by the observation that the nuclei of male and female reproductive cells undergo fusion in the process of fertilization. Soon thereafter, chromosomes were first observed inside the nucleus as thread-like objects that become visible in the …
