Targeted genome editing: Introducing the CRISPR/Cas9 system

...DNA by cutting it All living things contain DNA molecules, which carry the information required for life. Collectively, this information is referred to as the organism’s genome. The individual units of information within each DNA molecule are known as genes. DNA molecules are formed as chains of smaller molecules called nucleotides. The order in which these smaller...

Bioinformatics: a new asset in the Disease Detectives toolkit

...DNA sequencing and metagenomics are helping scientists identify hidden pathogens, solve medical mysteries and improve disease diagnosis faster than ever before...Imagine you are a doctor faced with a mystery illness. Your patient’s symptoms are getting worse, and none of the usual treatments are working. Normally, you would identify the culprit by growing the pathogen...

Further uses of genetic testing

...DNA. Scientists can analyse it to make something called a DNA profile. This is a bit like a fingerprint, and it can allow someone to be identified using just their genetic makeup. DNA profiling has lots of important uses and can even help solve crimes. This is called forensic testing. In this process, a suspect’s unique DNA profile is compared to DNA found at a crime...

Understanding interstrand crosslink repair in Drosophila

...DNA becomes damaged? One OU PhD student explains how studying interstrand crosslinks in fruit flies has exploited similar human disorders...Genomic stability and DNA repair are key factors in human health. When repair mechanisms are defective, humans become predisposed to a range of cancers. One kind of DNA damage for which effective repair is vital to humans,...

The science of genetics

...DNA deduced by Watson and Crick. By the end of the 20th century, many thousands of genes had been discovered and their sequences determined, including many that have roles in disease. These genes are scattered throughout the genome. Our genetic structure Every cell of a human being has two sets of twenty-three chromosomes and every cell of a given individual has exactly...

The metagenomics revolution: an introduction

...DNA or RNA from places such as soil, water, air, or the human body, metagenomics reveals the wide range of life that exists. While it is widely used in microbiology and health, metagenomics also has important applications in monitoring biodiversity in ecosystems, and supporting advances in biotechnology. This course will introduce the key ideas behind metagenomics and...
