Which best describes the outcome of dna replication?
a. the new dna molecule consists of one strand of dna.
b. the new dna molecule accumulates a new strand of dna with each replication.
c. the new dna molecule consists of one new strand and one old strand of dna.
d. the new dna molecule contains new dna, and the old molecule keeps the old dna.

C. The new DNA molecule consists of one new strand and one old strand of DNA.

DNA replication is a biological process that  makes two identical DNA molecules which are the replicas of the original DNA molecule. The double stranded DNA gets separated into two template strands. Each template strand act as a guiding strand for producing a counterpart called as complementary strand. Template and complementary strands combine to form a new double stranded DNA. Therefore, the new DNA molecule consists of one new strand (complementary strand) and one old strand (template strand) of DNA.
