Hello students, according to the mentioned question, thymeen dimer, thymein dimer results in mutations.
00:12
Let me consider it for the given question.
00:13
From the given options, we are going to select the correct method to reverse the thymine dimers that are formed by uv light.
00:29
Let us consider dimer.
00:31
These are formed when nucleic acids are expired light.
00:38
Mismatch base pairing occurs when nucleotides are exposed to ultraviolet light.
00:44
This mismatch base pairing occurs between nucleotides, that is thymine and thymine.
00:52
Since the present bonds are found between a and t and g and c.
01:01
This is commonly found according to the watson and crick base pairing.
01:10
But when the acids are exposed to ultraviolet light, the uv radiations induce thymine dimer formation.
01:22
The hydrogen bonds occurs in between two thymine nucleotides instead of the hydrogen bond between adenine and thymine.
01:31
Thymin dimers can be reverted back, can be reversed back using dna photolias enzyme.
01:43
The dna photolyase enzyme breaks the hydrogen bonds between two thymine resists...
