Two major sources of mutation are radiation and reactive oxygen species (ROS).The reactive oxygen species hypothesis for aging postulates that 

1) Senescence results from the accumulation of DNA, lipid, and protein damage inflicted by ROS of mitochondrial origin; and

2) Mitochondria of long-lived species should produce high ROS than do mitochondria of short-lived species.

3) the capacity of mitochondria to consume ROS might distinguish long-lived species from short-lived species, rather than differences in ROS generation.

Correct statements about RAPD’s

A. RAPD polymorphism is detected by using oligonucleotides usually more than 10 bases long of random sequences as primers in a reaction.

B. In a strain which has in genomic DNA sequences complementary to the primer oligonucleotide, PCR products will be detected in the gel,

C. Typical RAPD markers show limited variation between parents, especially in naturally inbreeding species.

D. RAPDs are more sensitive than RFLPs to experimental conditions making them more difficult to be consistent and reproducible.
