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: -Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.

Detailed explanation-3: -(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-4: -For this task, the genetic engineer uses a restriction enzyme. These enzymes recognize specific nucleotide sequences and cut the DNA at precisely those points. It is these enzymes that allow researchers to snip a gene out of the DNA sequence from one organism and splice it into the DNA of another.

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.
