What are the two types of DNA strands involved in replication?

• A. Parental (template) strand and Daughter (newly formed) strand.
• B. Original and Replicated strands.
• C. Template and Coding strands.
• D. RNA and DNA strands.

Answer: (A)

In DNA replication, the original strands act as templates to build new ones, so the two key strands are the parental (template) strand and the daughter (newly formed) strand. The parental strand provides the sequence pattern that guides the synthesis of a complementary daughter strand, and each newly formed DNA molecule ends up with one old template strand and one new strand. This is why the process is called semiconservative replication. The other terms (like coding vs template or mixing in RNA) don’t apply to the actual strands being copied—the strands that are replicated are DNA strands, with primers briefly guiding synthesis but not changing the fundamental naming.
