I would also say that the answer is C
Answer:
Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes frame shift mutations.
Explanation:
In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.
These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.
These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations
It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.
Answer:
Explanation:
According to hardy-weinberg principle that says in a large random mating population in the absence of migration,mutation and selection the gene and genotype frequency remains constant.
In a large random mating population the frequency of an Allele for white fur will remains in the population when there is no migration,mutation, or selection but the organism mate at random leading to production of offspring with similar Allele with there parents but when the population is small and random mating occur some allele will be selected against and lost in the population due to flunctuation in the population.
