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

Which of the following is incorrect option

(1) A change of single base pair in the gene results in the change of amino acid in case sickle cell anemia

(2) In case sickle cell anemia charged amino acid is changed to non polar amino acid

(3) Amino acid residue glutamine is changed to valine

(4) Sickle cell anemia is an example of point mutation

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

The locations in human genome which differ by a single base difference is known as

(1)Single nucleotide mutation

(2)Single nucleotide polymorphism

(3)RFLP

(4)Single nucleotide polymorphogenesis

Out of 64 codons how many of them code for amino acids?

(1) 64                            

(2) 20                            

(3) 61                            

(4) 32

Imagine an error occurring during DNA replication in a cell, so that where there is supposed to be a T in one of the genes there is instead a G. What effect will this probably have on the cell?
(1) The amino acid sequence of one of its kinds of proteins will be completely changed

(2) An amino acid will be missing from each of its kinds of proteins

(3) One of its kinds of proteins might contain an incorrect amino acid

(4) An amino acid will be missing from one of its kinds of proteins.

Mutations are:
(1) Heritable changes in the sequence of DNA bases that produce an observable phenotype

(2) Heritable changes in the sequence of DNA bases

(3) Mistakes in the incorporation of amino acids into proteins

(4) Heritable changes in the mRNA of an organism
