Answer:
combines genes from organisms of different species in a lab
Explanation:
Recombinant DNA technology involves the process of joining the genes (DNA) of different multiple species in order to insert into another organism (host). Recombinant DNA technology has many applications in genetic engineering. 
One example of Recombinant DNA is the synthesis of Insulin in bacteria cell where a human insulin gene is first inserted into a plasmid vector, then inserted into a bacterial cell that uses its expression abilities to transcribe and translate the gene into INSULIN protein.
This procedure is usually conducted in a laboratory with the use of certain laboratory equipments. 
 
        
             
        
        
        
Mitosis and meiosis is based off of cells in biology. Mitosis has to do with cells dividing into two identical cells with the same number of chromosomes. On the other hand, meiosis has to do with the parent cell losing half of their chromosomes and dividing twice in order to make four cells.
