Statement 1 is incorrect. Adenoviruses have double-stranded DNA genomes, not single-stranded DNA genomes.

Statement 2 is correct. The common cold is sometimes caused by adenoviruses, while AIDS (Acquired Immunodeficiency Syndrome) is caused by the human immunodeficiency virus (HIV), which is a retrovirus.

Therefore, only statement 2 is correct.
