Join the Amoeba Sisters as they discuss gene expression and regulation in prokaryotes and eukaryotes. This video defines gene expression and explains how gene expression relates to gene regulation ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

A collaborative effort has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of ...

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk", may actually play powerful roles in regulating gene expression. Focusing ...

CRISPR-Cas9 has been widely adapted for use in transcriptional modulation and epigenetic engineering with deactivated Cas9 (dCas9) systems to enable CRISPR interference (CRISPRi) and CRISPR activation ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk," may actually play powerful roles in regulating gene expression. Focusing ...

Origin-recognition complex, or ORC, plays an unexpectedly broad role in the regulation of human cell gene expression, according to a study in the journal Cell Reports. This is the first detailed study ...

Cancer tumors hijack the genetic program used by developing nerves. This is shown in a study published in the journal Frontiers in Genetics by researchers at Umeå University. In the long term, the ...

Primary immunodeficiencies are genetic disorders that impact on the immune system due to defective function of a variety of genes. Among those molecules are ...

Salk Institute researchers find new mode of epigenetic targeting, showing for the first time that genetic sequences can direct new DNA methylation patterns in plants LA JOLLA (November 21, 2025)—All ...
