Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.
As you're reading this sentence, the cells in your brain, called neurons, are sending rapid-fire electrical signals between each other, transmitting information.
Researchers at Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthesis.
The three types of rotavirus that cause gastroenteritis in individuals, known as groups A, B, and C, are the most well-known and afflict predominantly youngsters.
Metrion Biosciences Limited (“Metrion”), the specialist ion channel contract research and drug discovery company, today announced the appointment of Dr Benedetta Montagnini as Head of European Business Development. Driven by the uptake of its ion channel discovery services, the appointment follows the recent creation of a Client Services team as Metrion expands its operations and enhanced drug discovery capabilities, internationally.
Human DNA is neatly locked in place around a central disc in the tight quarters of the cell nucleus by H1 linker histone that helps shepherd DNA into the tidy chromatin fibers that make up chromosomes. The linker histone, on the other hand, is much more than a protein clip.
CRISPR has marked the beginning of a new era in genomic medicine. The popular CRISPR-Cas9 has generated plenty of potent methods for curing genetic diseases.
DNA "fingerprints" left behind by sea turtles offer scientists a simple, powerful way of tracking the health and whereabouts of these endangered animals, a key step forward in their conservation.
New study reveals that a family of proteins that help many different types of cells move and retain their form may induce disease when they work too hard and disturb the cellular environment.
Researchers at UT Southwestern have uncovered a molecular path that allows cells to detect when their lipid supplies are running low, triggering a flurry of activity that avoids starvation.
A new study provides a framework to boost crop growth by incorporating a strategy adopted from a fast-growing species of green algae.
Cells must divide many times before a new plant can grow from seed.
Working with tiny bacteria, Michigan State University researchers led by Lee Kroos have made a discovery that could have big implications for biology.
To celebrate National DNA Day 2022, News-Medical speaks to Jonas Korlach, Chief Scientific Officer of PacBio.
Scientists have known for years that amyloid fibrils -; fibrous, ropelike structures formed by closely linked protein molecules -; are present in the brains of patients with Alzheimer's and Parkinson's diseases and likely play a role in the progression of these disorders.
A Cornell University study describes a breakthrough in the quest to improve photosynthesis in certain crops, a step toward adapting plants to rapid climate changes and increasing yields to feed a projected 9 billion people by 2050.
In new research, UT Southwestern scientists report that imaging a key immunity protein known as STING at near-atomic resolution reveals a previously undiscovered binding location that appears to be crucial for launching immunological attacks.
Bacteria promote cancer metastasis by bolstering the strength of host cells against mechanical stress in the bloodstream, promoting cell survival during tumor progression, researchers report April 7th in the journal Cell.
If we want to enhance our knowledge and treatment of Alzheimer’s disease, we need to identify genetic risk factors.
Almost half of the U.S. adult population has high blood pressure - or hypertension - and about 20% of these patients have treatment-resistant hypertension.
Researchers have identified a family of proteins that is significantly elevated in the saliva of patients hospitalized with COVID-19.
