The insertion or deletion of a base pair into the genetic code will cause a frame shift mutation unless the number of base pairs inserted or deleted is:

(1) One

(2) Two

(3) three

(4) Ten

Haploids are more suitable for mutation studies than the diploids. This is because

(1) haploids are reproductively more stable than diploids

(2) mutagenes penetrate in haploids more effectively than is diploids

(3) haploids are more abundant in nature than diploids

(4) all mutations, whether dominant or recessive are expressed in haploids

Frameshift mutation occurs when

(1) base is substituted

(2) base is deleted or added

(3) anticodons are absent

(4) none of these

Given below is a representation of a kind of chromosomal mutation. What is the kind of mutation represented?

(1) Deletion

(2) Duplication

(3) Inversion

(4) Reciprocal translocation

The change in the reading frame will depend on

(1)no of bases deleted

(2)no of bases added

(3)no of bases deleted or added

(4)always change the reading frame either bases are deleted or added
