There are many different types of mutations which can arise in DNA. This diagram shows the normal order of the bases for one of the strands in a DNA molecule. Only one of the strands of DNA is ...

Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine ...

However, most DNA mutations do not alter a protein, they only alter it slightly so its appearance or function is not changed. There are many different types of mutations which can arise in DNA.

Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions ...

While some mutations have no effect on the organism, others can be harmful or even beneficial. To maintain the integrity of the genetic information, cells have evolved various DNA repair mechanisms.

Stanford scientists have identified 380 key genetic variants that significantly influence cancer development, filtering ...

Here we report a method for the enzyme-amplified electronic transduction of a single-base mutation in DNA. We apply Faradaic impedance spectroscopy and microgravimetric quartz-crystal microbalance ...

This was particularly evident in blood stem cells, where between 15 to 20 per cent of the mutations resulted from a specific type of DNA damage that persists for two to three years on average ...

Scientists have created a mega-database revealing how half a million different DNA mutations generate errors in proteins in humans. The researchers hope that the database will be used to develop ...

Stanford Medicine researchers sifted through thousands of single nucleotide mutations in DNA to identify fewer than 400 that are functionally associated with inherited cancer risk.

A groundbreaking study led by USC Assistant Professor of Computer Science Ruishan Liu has uncovered how specific genetic mutations influence cancer treatment outcomes-insights that could help doctors ...
