How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

How do scientists find their way around a chromosome? With chromosome maps called idiograms, researchers can pinpoint the locations of genes and locate abnormal gene forms. Aa Aa Aa Most ...

A new study reveals that the maternal X chromosome may accelerate brain ageing and increase Alzheimer's risk. Experiments on female lab mice showed th ...

In a nutshell Female cells randomly use either the maternal or paternal X chromosome—this study shows that relying more ...

Scientists at University of Oregon discover one of the oldest known animal sex chromosomes in California two-spot octopus.

A UCSF study reveals that maternal X chromosome expression may accelerate brain aging and cognitive decline. Female mice with ...

A new study recently discovered that the X chromosome the mother passes down may be responsible for accelerating brain ageing, which may result in an increased risk of Alzheimer's disease, among ...
