6. If mutation changes codon in such a way that there is no effect on functioning and sequence of protein. This type of mutation is termed as (1) Silent mutation […]
5. If substitution is the only possible type of mutation, then which technique would be no more useful for detecting them? (1) DNA sequencing (2) PCR amplification (3) Database searching […]
4. The frame shift mutation is induced by- (1) Nitrous oxide (2) Acradines (3) EMS (4) UV rays Frame shift mutations occur due to insertion or deletion of nucleotides not […]
3. Point mutation in which there is deletion or addition of one base pair is termed as (1) Deletion (2) Transition (3) Transversion (4) Frame shift mutation A point mutation […]
2. A single base pair mutation occurs in strand and mutant strand has a sequence CATTACCG, while its complementary strand has a sequence GTTATGGC. It means mutation has changed base […]
1. Which one of the following situations could be termed as intergenic suppression of a mutation in a coding sequence? (1) A nonsense mutation in the codon leading to lack […]

94. The following figure depicts the relationship between a genetic map for four genes (A, B, C and D) and their corresponding physical map. The following statements are made to […]
A series of ceil lines was created by fusing mouse and human somatic cells. In mouse-human somatic cell hybrids, human chromosomes tend to get lost before becoming a stable cell […]
Three somatic hybrid ceil lines, designated as X, Y and Z, have been scored for the presence or absence of chromosomes 1 through 8, as well as for their ability […]
