Two or more codons coding for one amino acid
non-ambiguous
degeneracy of codon
non-overlapping of codon
non-sense codon
Haploids are more suitable for mutation studies than the diploids.This is because
haploids are reproductively more stable that diploids
mutagens penetrate in haploids more effectively than in diploids
haploids are more abundant in nature than diploids
all mutations whether dominant or recessive are expressed in haploids
Mutation is more common when it is present in
recessive condition
dominant condition
constant in population
None of the above
Which one of the following does not follow the central dogma of molecular biology?
Pea
Mucor
Chlamydomonas
HIV
The one aspect which is not a salient feature of genetic code, is its being
degenerate
ambiguous
universal
specific
When a mutation is limited to the substitution of one nucleotide for another it is called
translocation
point mutation
base inversion
sugar phosphate deletion
Number of nitrogenous bases in a codon is
3
2
1
5
During transcription, the nucleotide sequence of the DNA strand that is being coded is ATACG, then the nucleotide sequence in the mRNA would be
TATGC
TCTGG
UAUGC
UATGG
In E.coli, which of the following classes of plasmids are found?
