Genetics is the study of heritable changes in gene activity or function due to the direct alteration of the DNA sequence. Such alterations include point mutations, deletions, insertions, and ...

In eukaryotic cells, chromosomes are made up of DNA. DNA can also be found in the chloroplasts and mitochondria, and inside the cytoplasm in the form of plasma. DNA molecules consist of nucleotides ...

Histones are a family of basic proteins that associate with DNA in the nucleus and help condense it into chromatin. Nuclear DNA does not appear in free linear strands; it is highly condensed and ...

Although synthetic processes inspired by life’s chemistry are inherently messy and complex, they may yet yield to bioengineers’ attempts to impose order. For example, engineers have been reporting ...

Scientists now have a better understanding of how short DNA strands decompose in microseconds. A research team found new fragmentation pathways that occur universally when DNA strands are exposed to ...

Everyone’s DNA sequence is unique. But for those who wish to maintain their genetic privacy, it may not be unique enough. A new study argues that more than half of Americans could be identified by ...
