Researchers identify the biosynthesis mechanism of new DNA nucleobases

DNA is made up of nucleobases, which are depicted by the letters G, A, T, and C. They are the foundation of the genetic code.

Study analyzes how ecological specialization occurs in marine species

In contrast to terrestrial biota, aquatic species with planktonic larvae can sustain massive population sizes.

Broader use of gene reserves helps conserve endangered species

According to studies, UK conservationists support the increased usage of Gene Conservation Units to help conserve some of the world’s rarest plants.

Cancer cells re-organize DNA structure to ramp up the activity of oncogenes

A lot of biological mechanisms go wrong in cancer—for example genes mutate and cells proliferate in an uncontrollable manner.

The history of the Amazon Basin affects the distribution of manatees

All three species of manatee now present on Earth share a common ancestor from which they split some 6.5 million years ago, when a huge lake in Amazonia, then linked to the Caribbean, was cut off from the sea.

Ulsan genome project reaches milestone of sequencing 10,000 whole genomes

UNIST and Ulsan City officially announced that their ambitious 10,000 Genome Project has finally reached the milestone of sequencing 10,000 whole genomes. On this day, they also held a declaration ceremony to commemorate the successful completion of the Ulsan 10,000 Genome Project, which was initiated in 2016 as part of the Genome Korea in Ulsan Project launched in 2015.

São Tomé island has two different species of caecilians, shows new study

The Gulf of Guinea islands harbor an abundance of species found nowhere else on Earth. But for over 100 years, scientists have wondered whether or not a population of limbless, burrowing amphibians--known as caecilians--found on one of the islands is a single or multiple species.

Mutations in GEMIN5 protein can cause rare genetic disorders in children

Researchers have discovered a genetic cause of an unusual neurological disorder characterized by developmental delay, known as ataxia.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.

Lack of functional GAS2 gene causes severe hearing impairment in mice

A gene called GAS2 plays a key role in normal hearing, and its absence causes severe hearing loss, according to a study led by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Genomic Analysis for the Conservation of Koalas

In this interview, AZoLifeSciences speaks to Professor Parwinder Kaur about her latest research that uses genomic analysis for the conservation of koalas.

Highly efficient method to identify the genetic “switches” that control gene expression

Scientists have created a high-throughput method to help explain and regulate gene expression for the treatment of diseases like beta-thalassemia and sickle cell disease.

Study defines genetic positions associated with the progression of Parkinson’s disease

The progression of Parkinson’s disease (PD) is an important factor in patients’ well-being and clinical trials.

Study reveals that bacteria DNA signals can be read either forward or backward

Bacteria’s DNA signals have symmetry that allows them to be read either backward or forward, challenging the current understanding of gene transcription.

Study suggests that bubonic plague had long-term impact on human immune genes

Scientists examining the remains of 36 bubonic plague victims from a 16th century mass grave in Germany have found the first evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.

New open-source image library illustrates content on genome-editing and their use in plants

Are you looking for clear, accurate images to bring your content on genome-editing and genetic modification to life? The John Innes Center has launched an open-source image library for journalists, writers and picture editors seeking to illustrate content on these important technologies and their use in plants.

Researchers map unique genetic profile of osteocytes for the first time

Researchers have mapped the specific genetic profile of the skeleton’s “master regulator” cells, called osteocytes, for the first time.

Research uncovers how antibiotics target bacterial RNA Polymerase to inhibit gene transcription

The emergence and spread of new forms of resistance remains a concern that urgently demand new antibiotics. Transcription is a vital process in bacterial cell, where genetic information in DNA is transcribed to RNA for the translation of proteins that perform cellular function.

Researchers sequence genome of raccoon dogs that are reservoir hosts for coronaviruses

For the first time, a research team has sequenced the genome of a raccoon dog. Genetic data now supports the animal’s ability to spread SARS-CoV-2.

New technology efficiently detects gene mutation in blood with low error rate

Next-generation gene sequencing (NGS) technologies --in which millions of DNA molecules are simultaneously but individually analyzed-- theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream.
