FireChat, the clever app that lets people talk to each other without using cell reception, just got an update that gives its users fixed handles. That might not mean a damn thing to you, which is understandable. FireChat doesn't have the name recognition of Snapchat.
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.

A bacterial DNA transposon. A transposable element (TE or transposon) is a DNA sequence that can change its position within the genome, sometimes creating or reversing mutations and altering the cell's genome size.etroviruses can also be considered TEs. For example, after entering a host cell and conversion of the retroviral RNA into DNA, the newly produced retroviral DNA is integrated into the genome of the host cell. These integrated DNAs represent a provirus of the retrovirus.
