Replication of DNA is a semiconservative process. This means that

Each new DNA molecule is made of pieces of the parent strand alternating with segments that have been newly constructed from free nucleotides

Solution

The correct option is C Each strand of the original, double stranded DNA molecule serves as a template for a newly constructed, complementary strand
Replication of DNA is a semiconservative process as the two strands of the parent DNA molecule act as templates for the synthesis of the complementary strands, such that two daughter DNA are formed each with one parent DNA strand and other a newly synthesized strand.
So, the correct answer is 'Each strand of the original, double stranded DNA molecule serves as a template for a newly constructed, complementary strand'
