Abstract Muller found halving gene dosage, as in males with one X chromosome, did not affect specific gene function. Why then was dosage "compensated?" This paradox was solved by invoking collective ...

Novel Regulator Of Chromosome Function Characterized Date: March 12, 2008 Source: Stowers Institute for Medical Research Summary: New light has been shed on a novel histone acetyltransferase ...

We propose that chromosome function is governed by internal mechanical forces generated by programmed tendencies for expansion of the DNA/chromatin fiber against constraining features. Chromosomal ...

Virtually all female mammals have two X chromosomes, but one of the chromosomes is basically inactivated, in other words it’s thought that most genes there aren’t performing any functions. Silencing ...

Function of sex chromosomes in turtles Date: July 26, 2021 Source: Iowa State University Summary: A new study sheds light on how organisms have evolved to address imbalances in sex chromosomes ...

X and Y chromosomes determine not only the sex of an individual, but many broad characteristics as well. From grip-strength to aggression, there are myriad differences between men and women beyond ...

A groundbreaking study reveals that sex chromosomes, especially through genes ZFX and ZFY, play a critical role in regulating gene expression across the human body, challenging traditional views of ...

Using data from 9,000 individuals, the researchers studied Y-chromosome gene function in patients with various types of cancer. The findings showed that cancer risk increases with loss of function of ...

Scientists have used gene editing to remove the extra chromosome causing Down syndrome in lab-grown cells. A major step ...
