What are the three basic steps involved in genetically modifying an organism?

Identification of DNA with desirable genes, introduction of the identified DNA into the host, and maintenance and transfer of the DNA to its progeny

The correct answer is Option -(3) Identification of DNA with desirable genes, introduction of the identified DNA into the host, and maintenance and transfer of the DNA to its progeny

Genetic engineering: Techniques to alter the chemistry of genetic material (DNA and RNA),to introduce these into host organisms and thus change the phenotype of the host organism.

There are three basic steps in genetically modifying an organism —

(i) identification of DNA with desirable genes;

(ii) introduction of the identified DNA into the host;

(iii) maintenance of introduced DNA in the host and transfer of the DNA to its progeny

The three basic steps involved in genetically modifying an organism are:

1. Identification of DNA with desirable genes: The first step is to identify the specific DNA sequence or gene of interest that carries the desired trait or characteristic.
2. Introduction of the identified DNA into the host: The second step involves inserting the identified DNA or gene into the genome of the host organism. This is usually done using vectors, such as plasmids, which can carry and deliver the DNA to the host cells.
3. Maintenance and transfer of the DNA to its progeny: After the DNA is introduced into the host, it needs to be maintained and replicated during cell division so that it can be passed on to the next generation of cells and progeny organisms.

These steps are essential in the process of genetically modifying an organism and allowing it to express the desired trait or characteristic conferred by the introduced DNA.
