The father of term biotechnology is Karl Ereky and father of
biotechnology is Louis Pasteur

PhD is a threshold qualification about research, & makes capable to present your idea/view as a Philosopher.

define serum is the artificial serum made by man and
composition of which is well known by us
characterized serum is that which made up of specific
characters for example it contains specific antibody against
specific disease
stander serum is serum which is collected from normal blood
which we can not make in laboratory scale although we know
composition of it.

Why, bacteria eat almost anything they can get! Of course,
they can't chew through cement. They can eat anything
edible to animals and humans, probably more! Take wood for
example, termites eat wood, bacteria eat wood too. In fact,
termites wouldn't even be able to eat wood if it wasn't for
the bacteria in their stomachs!

Bacteria are decomposers. Decomposers eat anything dead and
once they are finished they put nutrients from the dead
object or plant back into the ground to grow new plants

Transfection:Transfer of naked dna into eukaryotic cell

Transduction:Trnsfer of genetic material from bacteria to
virus through bacteriophage

Transfection- (Transfer+ Infection)transfer of naked DNA
(DNA without any carrier)into an Eukaryotic cell.
Transduction-Transfer of genetic material among bacteria by
carrier (bacteriophage).
Since the term 'Transformation' is used in case of transfer
of naked DNA (through non viral particles) into
prokaryotes,while the term 'Transfection' is uused in case
of eukaryotes because the term transformation is used for
the conversion of normal body cells into cancerous cells
which undergo unlimited cell division, so to avoid the
confusion between these two different cell processes the
other term Transfection is used in eukaryotes in place of
the term transformation in prokaryotes.

eukaryotes does not contain restriction modificayion system

it is used to determine the protein from a mixture of compounds

diazobenzyloxymethyl paper that binds all single-stranded DNA, RNA, and proteins by means of covalent linkages to the diazonium group; used in situations where nitrocellulose blotting is not technically feasible

positively charged i.e,cationic nature

rna is having _ve charge & DBM paper having positive chrg
hence due to thease opposite charges DBM paper binds to RNA
