D
Random direction
Verified step by step guidance
1
Understand the role of DNA polymerase: DNA polymerase is an enzyme responsible for synthesizing new DNA strands during replication.
Recognize the directionality of DNA strands: DNA strands have directionality, characterized by a 5' (five prime) end and a 3' (three prime) end.
Identify the synthesis direction: DNA polymerase adds nucleotides to the 3' end of the growing DNA strand, meaning it synthesizes DNA in the 5' to 3' direction.
Consider the implications of directionality: The 5' to 3' synthesis direction is crucial for the replication process, ensuring that the new strand is complementary to the template strand.
Review the options given: Among the options provided, the correct direction for DNA polymerase synthesis is 5' to 3'.
