DNA Synthesis
The natural or artificial creation of DNA molecules, involving the assembly of nucleotides in a specific sequence.
5' to 3'
Refers to the orientation of nucleic acids, indicating the direction in which DNA and RNA are synthesized.
DNA Strand
A long, linear molecule made of nucleotides that carry genetic information crucial for cellular function and heredity.

Final Answer :
C
Explanation :
DNA synthesis proceeds from the 5' to the 3' end of the DNA strand. This is because DNA polymerase can only add new nucleotides to the 3' end of the growing strand. Therefore, the synthesis proceeds in the direction from the 5' to the 3' end, corresponding to the direction from the phosphate group (5') to the hydroxyl group (3') of the growing strand.
