What is recombination? Discuss the applications of recombination from the point of view of genetic engineering.

Explanation

### Step-by-Step Solution:

**Step 1: Define Recombination**
Recombination is the biological process that results in the exchange of genetic material between different DNA molecules, leading to the formation of new combinations of genes. This process often occurs during meiosis, where homologous chromosomes exchange segments of DNA, resulting in genetic variation.

**Step 2: Explain the Mechanism of Recombination**
During recombination, two strands of DNA (for example, from gene 1 and gene 2) come together and undergo a crossing-over event. This involves the breaking and rejoining of DNA strands, which leads to the mixing of genetic information. The result is the formation of new gene combinations that were not present in the parent organisms.
