Answer:
The correct answer will be option C (Two new complementary strands of DNA will be built).
Step-by-step explanation:
DNA replication is a process by which a cell makes exact copies (replicas) of its genetic material or DNA. DNA replication takes place during the S-phase or synthesis phase of the cell division.
DNA replication is complex process in which two strands of DNA are separated by an enzyme called helicase which melts hydrogen bond between two base pairs.Then, separated strand in 3'-5' direction polarity acts as a template strand or leading strand while 5'-3' direction acts as lagging strand.
New complimentary strands are formed by an enzyme called DNA polymerase which adds new nucleotides to the growing DNA chain by forming hydrogen bond between complimentary base pairs. Therfore, from ds-DNA molecule, two new complimentary strands are formed making exact copies of the DNA. This method is known as semi-conservative replication.
Hence, option C-two new complementary strands of DNA will be built is the correct answer.
