A scientific team says it has pinpointed the crucial steps in the beginning of the DNA replication process, including surprising structural details about the enzyme that unzips and splits the double ...

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 ...

Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

"This was truly collaborative work where molecular biology expertise from Christian Speck's lab at Imperial College, London, Bruce Stillman's group at Cold Spring Harbor Laboratory, and the ...

Deoxyribonucleic acid (DNA), is the macromolecule that holds all hereditary and genetic information. Continuously under assault, alterations and damage to DNA can lead to many different health issues, ...
