How many genes are present in E.coli?
None of these
In E.coli, which of the following classes of plasmids are found?
all of these
The number of punctuation codons in a genetic code are
Signaling between cells usually results in the activation of protein
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
RNA polymerase stops its activity by
sigma (σ) factor
What is antisense technology?
A cell displaying a foreign antigen used for synthesis of antigens
Production of somaclonal variants in tissue cultures
When a piece of RNA that is complementary in sequence is used to stop expression of a specific gene
RNA polymerase producing DNA
The one aspect which is not a salient feature of genetic code, is its being
The technique involving insertion of a desired gene into the DNA of plasmid vector is known as
When a mutation is limited to the substitution of one nucleotide for another it is called
sugar phosphate deletion
