Transcription factors are proteins that interact with DNA to regulate the function of some genes. Generally, a single transcription factor binds to several regions in the genome as it orchestrates complex cellular responses, which require the activation or inhibition of several genes.
A new animal study has identified a gene essential for the early development of basic social behaviours.
Little is known about how social behavior develops in the earliest stages of life. But most animals––including humans––are born with an innate ability to interact socially or form bonds with others. And that contributes to success throughout life.
An international study led by the medical Faculty of the University of Bonn has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations of various organ systems can result.
Genetic mutations kick start cancers. Some mutations shuffle the genetic code, others come from the deletion of key genes.
