- What is biotechnology?
Biotechbiological knnology owledge to obtaiis the application on newf (^)
techniques, materials and compounds of
pharmaceindustrial and scientificutical, medical, agrarian, use, i.e., of (^)
practical use.
The pioneer fields of biotechnology were
agriculture anowadays many nd the food industry bother practical fieldsut (^)
use its techniques.
- What is genetic
engineering?
Genetic engineering is the use of
genetic knowledge to artificiallymanipulate genes: It is one of the fields (^)
of biotechnology.
- At the present level of the
biotechnology what are the
main techniques of genetic
engineering?
The main techengineering today niques of geneticare: the recombi (^) nant
DNA technoloengineering itself) igy (also called n which pieces ofgenetic (^)
genes from an organism are inserted
into the genetic material oorganism producing recombinantf another
beings; the nucleus transplantation
technology, popularly “cloning”, in which a nucleus of a cell isknown as (^)
grafted into a enucleated egg cell of the
same species to the donor (of the nucleus) increate a genetic copy dividual; of
the technology of DNA amplification, or
PCR (pallows millions rolymerase ceplicationshain reaction), of chosen that
fragments of a DNA molecule.
The recombinant DNA tused to create transgenic organisms,echnology is (^)
like mutant insulinThe nucleus transplantation t-producing bacteria.echnology (^)
is in its initial development but it is thebasis, for example, of the creation of
“Dolly” the sheep. PCR has numerous
practicaldetect microor uses, as in ganismsmedical tests to present in blood (^)
and tissues, DNA fingerprint and

- What are restriction
enzymes? How do these
enzymes participate in the
recombinant DNA technology?
Restrictionendonucleases, enzymes, or are enzymes sprestrictionecialized (^)
in the cutting of DNA fragments each
acting molecule. upon specific sites of the DNARestriction enzymes are used (^)
in the recombinant DNA technology to
obtain with pmolecules to brecision pe later insieces oerted into othf DNA (^) er
DNA molecules cut by the same
enzymes.
