Detailed explanation-1: -When genetic information is moved from one cell to another to change the characteristics of the cell, the procedure is known as genetic: engineering. Changing a characteristic by removing and inserting genes into DNA is known as gene: splicing.

Detailed explanation-2: -(SPLY-sing) The process by which introns, the noncoding regions of genes, are excised out of the primary messenger RNA transcript, and the exons (i.e., coding regions) are joined together to generate mature messenger RNA.

Detailed explanation-3: -Insertion of genes into such a large DNA molecule is accomplished via small insertion vectors, as described previously for vaccinia. Viral and insertion vector DNA are simultaneously introduced into insect cells by direct uptake using calcium phosphate.

Detailed explanation-4: -Definition. Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism.

Detailed explanation-5: -Gene splicing is the process of chemically cutting DNA in order to add bases to the DNA strand. The DNA is cut using special chemicals called restriction enzymes, . Gene splicing is the removal of introns from the primary transcript of a discontinuous gene during the process of Transcription.
