IOException Example in Java. In this tutorial I am going to explain one of the most common Java exception that is well known by all the Java developers. IOExceptions are thrown when there is any input / output file operation issues while application performing certain tasks accessing the files.
Understanding Oxidative Stress. Like an apple turns brown when exposed to air, our cells can ârustâ when we breathe due to oxidative stress, a process caused by free radicals. Free radicals are unstable molecules that damage or âoxidizeâ cells throughout the body in a process called oxidative stress.
This oxidative stress can directly damage DNA. It is the associated repairing of the oxidatively damaged DNA that sometimes fails, thus creating a mutation in the DNA. 3) Direct attachment of chemicals to DNA forming DNA Adducts.These 'adducts' must be removed from the DNA by DNA Repair mechanisms.t is the associated repairing of the oxidatively damaged DNA that sometimes fails, thus creating a mutation in the DNA. 3) Direct attachment of chemicals to DNA forming DNA Adducts.
