WHEN A DNA MOLECULE IS COPIED TO MAKE ANOTHER DNA MOLECULE, WHICH STATEMENT BEST DESCRIBES THE RESULTING STRANDS?
A. ONE DOUBLE STRANDED DNA MOLECULE IS THE ORIGINAL AND THE OTHER A NEW COPY
B. BOTH RESULTING STRANDS ARE ENTIRELY MADE OF NEW DNA BASED ON THE INFORMATION IN AN ORIGINAL STRAND
C. EACH RESULTING DOUBLE STRANDED DNA MOLECULE CONTAINS ONE ORIGINAL STRAND ONE NEWLY CONSTRUCTED STRAND
D. EACH SINGLE STRAND OF NUCLEIC ACID IS MADE OF A MIX OF OLD AND NEW NUCLEOTIDES
In the future, please do not use capital letters. In computer language, it is considered impolite, much like shouting. Actually, it's much more difficult to read!

C : EACH RESULTING DOUBLE STRANDED DNA MOLECULE CONTAINS ONE ORIGINAL STRAND ONE NEWLY CONSTRUCTED STRAND
The correct answer is C. Each resulting double-stranded DNA molecule contains one original strand and one newly constructed strand.
When a DNA molecule is copied, it undergoes a process called DNA replication. During replication, the two strands of the DNA molecule separate, and each strand serves as a template for the synthesis of a new complementary strand.
In the process, an enzyme called DNA polymerase adds new nucleotides to the template strands based on the complementary base pairing rule (A with T, C with G). This results in the formation of two new double-stranded DNA molecules, each containing one original strand and one newly constructed strand.
Therefore, option C correctly describes the resulting strands of DNA replication.
