The skin and mucous membranes act as primary physical barriers in innate immunity, preventing pathogen entry. Phagocytosis by macrophages and neutrophils is a non-specific (innate) cellular defense mechanism, not a specific immune response. Memory B and T cells are produced during the primary specific immune response and provide rapid, long-lasting immunity upon re-exposure. Thus, statements 1 and 3 are correct.

Explanation:
DNA contains adenine, guanine, cytosine, and thymine. RNA contains uracil instead of thymine. This is one of the key differences between DNA and RNA. Uracil pairs with adenine in RNA. The base pairing in DNA is A-T and G-C. In RNA, it is A-U and G-C. Uracil lacks the methyl group present in thymine.
