The last few years have provided us with a new level of understanding of how chromosomes are replicated, segregated and read - and how their 3D organisation influences expression of individual genes ...

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 ...

The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the biological sex, reproductive organs, and sexual characteristics that develop in a person.

"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 ...

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 ...

Chromosomes are cellular structures that contain the genetic material. A chromosome is comprised of a single DNA molecule that may be either circular or linear. The full complement of a cell s ...

Excess liquid was removed and 4′,6-diamidino-2-phenylindole (DAPI) (Sigma, St. Louis, MO, United States) in the antifade solution Vectashield (Vector, Burlingame, CA, United States) was added to ...

Cytogenetics is a pioneer field within genetics and emerged when chromosomes were revealed as the gene carriers in the early twentieth century, long before the discovery of the DNA structure. For ...

For a while there, it seemed like a crudely drawn webcomic had DreamWorks Animation’s number. In an unflattering contrast to the imaginative movies that Pixar was making in the ‘00s ...

1, 2025 — A research team has clarified a mechanism of how retrotransposons, genetic elements that can 'jump around' chromosomes and are known drivers of evolution, preferentially insert in the ...

The team believes that the structure was in use until the 8th century BCE, the middle of the period when the Kings of Judah ruled. A scarab seal from the 8th century BCE uncovered during the ...
