DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Recombineering technique may overcome barriers in bacterial engineering

Genetic engineering of bacteria has transformed contemporary medicine, from bacterial-based insulin to a deeper insight into infectious diseases.

gnomAD Consortium releases first set of discoveries on human genetic variation

For the last eight years, the Genome Aggregation Database Consortium (and its predecessor, the Exome Aggregation Consortium, or ExAC), has been working with geneticists around the world to compile and study more than 125,000 exomes and 15,000 whole genomes from populations around the world.

Study shows how ocean virus captures the metabolism of carbon-storing bacteria

Below the surface of the ocean, a virus is stealing the metabolism of the most abundant organism present on Earth. That might be attractive to those who breathe above the ocean’s surface.

Using CRISPR/Cas molecular scissors to recombine entire chromosomes

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants.

New minimally invasive method allows cells to be sampled over time

At any given moment, a variety of dynamic processes occur inside a cell, with many developing over time. Because current research methods for gene profiling or protein analysis destroy the cell, study is confined to just that one moment in time, and researchers are unable to return to the cell to examine how things change beyond that snapshot.

Mechanically rejuvenated fibroblasts show promise in stem cell engineering

Fibroblasts synthesize the collagen, creating the structural framework for animal tissues, and play a significant role in the process of wound healing.

New sequencing method helps map the spatial arrangement of DNA

A sequencing technique helps to map the spatial arrangement of DNA in the cell nucleus, revealing which regions of the genome are at greater risk of mutation.

Study finds strong link between fermented foods and the gut microbiome

According to a new international study, fermented foods can be the main source of potentially probiotic lactic acid bacteria (LAB) for the human gut.
