Created with Sketch. Angelman syndrome is caused by an over-expression of paternal imprinted genes and an under-expression of maternal ones on chromosome 15. Children with this genetic disorder ...

Two relatively frequent syndromes involve chromosome 4 and may coincide in the same person in the form of a ring chromosome 4. Formation of a ring chromosome 4, r(4), often involves loss of 4p and 4q ...

"Given the fact that the X chromosome is enriched for brain-related genes, it became very important for us to know what roles it might be playing in brain aging," said Samira Abdulai-Saiku, Ph.D ...

Summary: New research shows that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and paternal X ...

But some plants have taken a different approach. They have evolved sex chromosomes, the bits of DNA that make individual plants either male or female. In that club are organisms like the ginkgo ...

Researchers at UC San Francisco found that female mice expressing only a maternal X chromosome experience faster brain aging and cognitive decline compared to those expressing both maternal and ...

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome. That's a big deal given that scientists didn't know until now if these oddball ...

Get Instant Summarized Text (Gist) The completion of the final synthetic chromosome in the yeast genome marks a significant advancement in synthetic biology. This achievement enables the creation ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. The X chromosome passed from mom to ...

Chromosome abnormality is the condition in a cell or organism where the number of chromosomes or the structure of any chromosome differs from the normal karyotype. When the variant genotype is not ...

It emphasizes the sequential arrangement of homologous genes, often focusing on their relative positions and orientation across chromosomes within or between species. It is often used to analyze ...
