Select which example are induced mutations.
a. nitrous acid causes the deamination of adenine to
b. transposition causes the formation of deletions.
c. errors in DNA replication cause the formation of point
d. ionizing radiation causes chromosomal fragmentation
Nitrous oxide caused domination of adenine to hypoxanthine induced mutation d. Ionization causes chromosomal fragmentation Ionization causes 2 types of induced mutation Direct induced mutation: If the chromosome gets mutated , by incident of ionizing radiation directly on DNA. Indirect induced radiation (mediated by free radical): If the ionizing radiation forms the free radical due to hydrolysis of H2O molecule , thus formed free radical leads to mutation of the chromosome . Both type of mutation leads to fragmentation of chromosome.
