ple answer this question
Answers
Genetic engineering is a branch of science that seeks to develop a trait or set of traits in an organism by inserting, or incorporating, a sequence of genetic code that is specific for that trait. Viruses are tiny, nonliving particles that must have a host cell to replicate and flourish. One of the qualities viruses have that makes them attractive to genetic engineering scientists is their ability to attach to and invade specific cells, and incorporate the DNA (and/or RNA) they are carrying into the host cell, where it combines with the host cell's DNA. This invasive quality viruses have provides scientists with a "key" to open the door to the DNA in the cell which they want to modify.
Viruses, not all, are used as the medium of genetic engineering as these viruses have the capability of delivering a new gene by cell infection.
Explanation:
- Viruses are used extensively as vectors in genetic engineering.
- This type of engineering deals with the identification of genetic properties and modifying them and including them to curb ailments, to solve epidemic problems, to help the food technology and others.
- Viruses are used as these have the capability of introducing a new gene to a cell by infecting thus cell.
- The vectors are modified to remove their own infectious property and these cannot create any disease on humans when used.
