What can cause changes in DNA sequences? Changes – or mutations – in DNA sequences can be caused by many different factors. There are different types of gene mutations and they can affect anything ...

A new study shows that over 99% of the human genome can be accurately assembled by focusing on 65 diverse humans.

Since the sequence of the human genome and that of other organisms such as the mouse and fruit fly ... the team at IRB Barcelona observed that the mutations also accumulated every 10 DNA base pairs.

A Z-T base pair would thus hold DNA's double helix together a bit more than a standard A-T ... One of their main forms of defense are enzymes that recognize specific sequences in DNA and cut them.

With a regular human genome consisting of 46 chromosomes and around 20,000 genes made up of 3 billion base pairs of DNA, just a slight alteration to our genetic code is enough to cause us disease.

DNA is a double-helical molecule that stores all the instructions a cell requires to sustain itself. The information is encoded within the specific sequential order of genetic letters (DNA base ...
