Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

Diseases and conditions found only on the X chromosome are said to be sex-linked, as are rare Y-linked conditions such as male infertility. The X chromosome is larger and commands more regulatory ...

Measuring the telomeres of 147 people for this study, the researchers found in one individual that the average telomere length across all chromosomes was 4,300 bases of DNA. Then when they ...

A 2022 study published in the journal PNAS found that the important Y chromosome genes could be capable of relocating to other genes, as observed in mice. There is also the possibility that humans ...

Remarkably, the evidence suggests the Cohanim chromosomes coalesce at a date that corresponds with when the priesthood is thought to have begun. What researchers may have found is a marker ...

Instead of the linear chromosomes found in mammals, the team crafted a circular chromosome, which is compatible with DNA replication in yeast. They then assembled the HAC inside budding yeast. By ...

In particular, she found an unbalanced pair of chromosomes in male cells, and she named these structures "heterochromosomes." Similarly, American geneticist E. B. Wilson worked with several ...

Chromosomes that lack centromeres segregate ... Although significant differences have been found in the molecular composition of centromeres in different species, the function of all eukaryotic ...

Women have a higher proportion of key immune cells between puberty and menopause, which may be linked to the sex hormone estrogen and explain why they are less susceptible to certain infectious ...
