The accurate distribution of chromosomes in an oocyte is essential for the correct transmission of genetic information to the ...

Moreover, a very large part of the Y chromosome that was missing from the previous version of the Y reference is satellite DNA – large, highly repetitive regions of non-protein-coding DNA. On the Y ...

The most important part of the Y chromosome is the master sex gene called SRY, which triggers a fetus' development as a biological male. "The X and Y were once upon a time just an ordinary pair of ...

The study appears in Nature.. The research focused on parts of chromosomes known as human accelerated regions (HARs), which have evolved most rapidly since humans split from chimpanzees on the ...

The Y chromosome is the smallest chromosome, and holds the least amount of genes, but scientists are still learning about all of its biological functions. Research has shown that many men start to ...

Some parts of the chromosome have the puzzle pieces inverted. And some stretches of DNA contain palindromes; the DNA letters read the same in both directions.

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males ...

The central part of each nucleosome (core particle) is a cylindrical structure (5.7 nanometers in height and 11 in diameter) ...

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share ...
