Modern crop breeding is entering a new era of genome design, led by genome editing technologies as mainstream tools for targeted genome modification. In a review published in Nature Reviews Genetics, ...

The Human Genome Project changed everything. A map of the entire human sequence of DNA was the starting point for an enormous number of discoveries, from disease genes to how humans evolved. But DNA ...

Humans have selectively bred animals and crops since the beginning of agriculture, but advances in biotechnology have provided genetic tools to select specific traits. First applied to animals in the ...

Genome editing is a powerful biotechnology tool that allows scientists to make precise changes to an organism's DNA. It involves the use of specialized enzymes, known as engineered nucleases or ...

Researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation. Researchers have determined ...

Could we genetically optimize human beings? This scenario, which sounds like something out of science fiction, has never been so close. It raises ethical questions, which Bertolt Meyer, who was born ...

An understanding of the origin and dynamics of heritable genetic variation within classical animal breeding programs is needed to provide the context for understanding the contributions and concerns ...

The rise of gene-edited embryos has raised a myriad of ethical questions. It involves altering DNA to prevent disease or even to choose specific traits using a method known as CRISPR. In 2018, Chinese ...
