DNA of $\phi \times 174$ bacteriophage has
1 48502 Nucleotides
2 5386 Nucleotides
3 5386 Nitrogen base pairs
4 48502 Nitrogen base pairs
Explanation:
Bacteriaophage $\phi \times 174$ is a single e-stranded DNA virus that infects Escherichia coli; and the first DNA based genome to be sequenced. In this bacteriophage, DNA is composed of 5386 nitrogen base pairs.
Shift-II

Which of the following nucleic acids is present in an organism having $70 \mathrm{~S}$ ribosomes only?
1 Double stranded circular DNA with histone proteins
2 Single stranded DNA with protein coat
3 Double stranded circular naked DNA
4 Double stranded DNA enclosed in nuclear membrane
Explanation:
$70 \mathrm{~S}$ ribosome are present in prokaryotic species like bacteria, which also lack a nucleus and have double-stranded, circular naked DNA in their cytoplasm that is not protected by the nuclear membranes.

Two enzymes responsible for restricting the growth of bacteriophage were isolated from
1 Salmonella
2 Agro bacterium
3 Escherichia Coli
4 Archea bacteria
Explanation:
The two enzymes responsible for restricting the growth of bacteriophage were isolated from E.coli. Restriction enzyme is a protein isolated from bacteria that cleaves DNA sequences at sequence - specific sites, producing DNA fragments with a known sequence at each end. The use of restriction enzymes is critical to certain laboratory procedure including recombinant DNA technology and genetic engineering.
