This video explains the stages of mitosis, contrasts them with meiosis and the creation of haploid gametes, and concludes by showing how gametes fuse during fertilisation to form a zygote.

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

Scientists have discovered that DNA behaves in a surprising way when squeezed through tiny nanopores, overturning a long-held assumption in genetics research. What researchers once thought were knots ...

In 1869, Swiss scientist Friedrich Miescher isolated a mysterious substance from cell nuclei—an overlooked finding that would later reshape biology and our understanding of life itself. A ...

James Dewey Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped launch a revolution in biology and medicine, died Thursday at age 97. He died in hospice care after a brief ...
