### Step-by-Step Solution 1. **Understanding Alien DNA**: Alien DNA refers to foreign DNA that does not belong to the organism in question. It is crucial to recognize that this DNA is not naturally part of the organism's genetic material. 2. **Structure of DNA and Chromosomes**: DNA is structured as a double helix, consisting of two strands. In eukaryotic cells, DNA is organized into chromosomes, which are made up of two sister chromatids. 3. **Recognition Sequences**: For alien DNA to integrate into a chromosome, it must have specific recognition sequences. These sequences are essential for the DNA to be recognized and ligated (joined) to the chromosome. ...
