Question

which best describes the newly synthesized dna strands after dna replication has occurred? they are composed of entirely new dna strands. they are a random mixture of new and old dna segments. each new molecule contains one old (parent) strand and one newly synthesized (daughter) strand. they are composed of entirely old dna strands.

Explanation:

DNA replication follows a semi - conservative model. In this process, the two strands of the parental DNA molecule separate, and each strand serves as a template for the synthesis of a new complementary strand. So, each new DNA molecule consists of one old (parental) strand and one newly synthesized (daughter) strand.

Answer:

Each new molecule contains one old (parent) strand and one newly synthesized (daughter) strand.
