Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell division ...

Unlike nuclear DNA, mitochondrial DNA (mtDNA) is circular in nature and organized as mitochondrial nucleoids comprised of DNA-protein complexes that are distributed in the matrix. It is also inherited ...

Fruit flies make for stingy mothers, imparting only a portion of the genetic building blocks their offspring need to survive. The rest must be produced by the fertilized egg in its first few steps of ...

For biologists everywhere, April 25 is auspicious. It is DNA Day and commemorates the date in 1953 when scientists Francis Crick, Rosalind Franklin, James Watson and Maurice Wilkins published seminal ...

Picture in your mind a traditional “landline” telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...
