The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

Several studies have shown that intelligence is only passed down from one parent, and all indicate that it is the mother who ...

Now nonchromosomal genes have been identified by the traditional methods of genetic analysis There has been evidence for many years that hereditary information exists apart from the chromosomal genes.

Females, on the other hand, usually carry two X chromosomes — one from mom and one from dad. But each cell needs only one X ...

How do sex chromosomes affect intelligence? Created with Sketch. The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the ...

The flowerpot snake, one of the world's smallest snakes, has some unusual distinctions. Also known as the Brahminy blind ...

The flowerpot snake, recognized as one of the smallest snakes globally, possesses some remarkable characteristics. Commonly ...

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance. Cornell ...

However, the genetic fragments tended to connect in unpredictable sequences of varying lengths, making it difficult to anticipate how the genes would behave. Furthermore, the constructs often attached ...

For one, inserting at the end of the chromosome helps the transposon avoid genes for the cell's core functioning, which reside in the middle of the chromosomes; transposons that can target the ...
