Question
The sites in the gene at which the mutations occur with unusually high frequency are referred to as
Open in App
Solution
The correct option is D Hot spots
Hot spots are the genetic loci which are more susceptible to mutations. The concept was given by Benzer who suggested that differential mutation rates for AT and GC are partly because of the surrounding bases. For example, misalignment of template during DNA replication produces long repeats which are highly prone to mutations. Smallest unit capable of undergoing recombination is called as recon. A recon consists of one to several mutons, which are the smallest unit of mutation. Palindromes are the DNA sequences that are read same in 5’ to 3’ direction on both strands; it does not affect the mutation rate. Correct answer is C.
