A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

Reef fish flip a genetic switch in response to warming seas

Reef fish species uniquely respond to climate change, with some more vulnerable than others.

Understanding evolution of early life may be trickier than previously thought

Biologists have long hoped to understand the nature of the earliest living organisms on Earth. If they could, they might then be able to say something about how, when, and where life arose on Earth, and perhaps by extension, whether life is common in the Universe.

DNA may not be the 'blueprint' for life, just a scrambled list of ingredients

The common view of heredity is that all information passed down from one generation to the next is stored in an organism's DNA. But Antony Jose, associate professor of cell biology and molecular genetics at the University of Maryland, disagrees.

Researchers develop new molecular workflow to study single-cell genomics of diseases

Although advances in genetics and genomics reveal numerous disease-associated gene mutations, physicians and researchers still wrestle with the tricky challenge of linking those mutations to actual disease-causing processes.

Reference genes could lead to genetic improvement in wheat

Wheat sustains the world. The FAO has stated that wheat is one of the main crops in the world, both in terms of scope and production, and it is also one of the rich sources of vegetable protein and carbohydrates in the human diet.

Scientists find gene signature linked to worst prognosis in rare uterine cancer

Women who don't survive a rare and aggressive uterine cancer called uterine serous carcinoma, have high expression of a group of 73 genes, a score scientists say can help identify these women and improve their outcome.

Researchers analyze genomic diversifications of five cotton lineages

Come harvest time, the cotton fields look like popcorn is literally growing on plants, with fluffy white bolls bursting out of the green pods in every direction.

A ‘virtual embryo’ for unprecedented single-cell studies

Researchers from EMBL Heidelberg and from the University of Padua School of Medicine have created the first complete description of early embryo development, accounting for every single cell in the embryo.

Researchers use genome-wide CRISPR technology to identify leukemia's weakness

A team of researchers at University of California San Diego School of Medicine and Moores Cancer Center used CRISPR technology to identify key regulators of aggressive chronic myeloid leukemia, a type of cancer that remains difficult to treat and is marked by frequent relapse.

Study reveals the formation of tuft cells and their role in immunity

Chronic pancreatitis, or persistent inflammation of the pancreas, is a known risk factor that leads to the development of pancreatic cancer, which is the third-deadliest cancer in the United States.

Study shows how human embryonic stem cells commit to early specialization

Scientists at the Francis Crick Institute have identified the point when stem cells in human embryos irreversibly commit to specialization.

Advanced simulations show how to improve efficiency of gene therapy

Diseases with a genetic cause could, in theory, be treated by supplying a correct version of the faulty gene.

Stem Cells In Embryos Commit To Specialization Surprisingly Early

The point when human embryonic stem cells irreversibly commit to becoming specialized has been identified by researchers at the Francis Crick Institute.

Histones Are Crucial For Adaptation To Cell Stress

The genetic material, DNA, of plants, animals, and humans is stored inside the cell, and DNA packing is guaranteed by proteins called histones.

Genetics Linked To Childhood Problems

Emotional, social and psychiatric problems in children and adolescents have been linked to higher levels of genetic vulnerability for adult depression.

Cancer Drug Resistance Study Raises Immune Red Flags

Sooner or later, most cancer patients develop resistance to chemotherapy drugs designed to kill their cancer, forcing oncologists to seek alternatives.

Novel protein facilitates a critical event in mammalian fertilization

Fertilization is a fundamental process in sexual reproduction when the combination of male and female gametes blends genetic material to create a new unique individual. Now, researchers from Japan have identified a new factor that may help orchestrate this vitally complex life event.
