Expert Solution

Q) Factors leading to degradation of DNA include all but

Humidity, time and temperature cause the degradation of DNA but there is no effect of darkness on the degradation of DNA.

Humidity: quantity of water vapor present in the air is called humidity and it is estimated in terms of relative humidity or absolute humidity. When the biological material exposed to the high humid environment which allows the rapid growth of bacteria and fungus which in turn cause the rapid degradation of DNA.

Time: time also causes the degradation of DNA. As the time increases the exposure of DNA to DNA degrading enzymes and free radicals also increased in biological samples which cause the degradation of DNA.

Temperature: high temperatures cause the degradation of DNA by depurination, deamination of cytosine residues and hydrolysis of phosphor diester bonds. At 190°C DNA is completely degraded.

light induces the degradation of DNA but intactness of DNA maintained by keeping in dark.
