The correct statement about the second DNA molecule produced during replication is:

**It is identical or nearly identical to the first DNA molecule.**

During DNA replication, each strand of the original DNA molecule serves as a template for the formation of a new complementary strand. As a result, the two resulting DNA molecules are nearly identical to the original molecule, each consisting of one original strand and one newly synthesized strand (this is known as semiconservative replication).
