If the DNA template has the
following sequence 5' TGATC 3'. When depurination occurs the
sequence that would occur in the daughter strand of the altered
strand is (d) 3'
AAG 5'
The given sequence of template is 5'TGATC 3'
In depurination the purines Adenine (A) and Guanine (G) are
removed. The daughter sequence being in 3' to 5' sequence forms
from the parent sequence.
TEMPLATE 5'TGATC 3'
DEPURINATION 5' TTC 3'
DAUGHTER 3' AAG 5'
DNA is under constant repair due to UV radiation, chemicals causing
mutations, and errors occured due to DNA replication. These various
damages cause the DNA dimerizaton process to depurination.
Depurinaion involves the removal of Purine bases from the DNA
sequence. This takes place by hydrolysing the covalent bond between
Purine Base and deoxyribose sugar and releases the purine base from
the sequence. This results in the mutations in further process of
DNA replication.
