Some genes are passed on from parent to offspring without ever being part of a nuclear chromosome ... The answer to this question lies in the location of the gene that determines leaf color.

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

How do sex chromosomes affect intelligence? Created with Sketch. The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the ...

has investigated how the chromosomal location affects epigenetic stability and gene expression through chromosome engineering. The results are published in the journal New Phytologist. Chromosomal ...

However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...

Chromosomes contain hundreds to thousands of genes, which are sections of DNA located at specific points on a chromosome. The Y chromosome is an exception, only containing a few dozen genes.

In a nutshell Female cells randomly use either the maternal or paternal X chromosome—this study shows that relying more heavily on mom’s X chromosome could speed up brain aging and memory decline The ...

UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

A high-quality genome assembly of Silene latifolia was generated by researchers at CNRS/Université Claude Bernard Lyon 1 and ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don ...
