Transitional Fossils Do NOT Exist
-Evolution Is A Slow Process
<span>Forensics uses special techniques to enhance the visibility of a bloody footprint. At times, a bloody footprint may not be visible to the naked eye. First, use ultra-violet light to detect bloody footprints in the area. Then, a chemical called Luminol can be used to create an impression of the bloody footprint.</span>

Answer:
C
Explanation:
The origin of replication refers to the site at which DNA replication begins. The process of DNA replication - which occurs prior to cell division - generates a new copy of the DNA.
DNA replication involves unwinding of the DNA double helix, creating a Y shape called the replication fork. The two strands are then replicated, and now there are two DNA molecules, each containing one "old" DNA strand and one "new" DNA strand.
The first stage at the origin of replication is that the enzyme helicase begins splitting apart the strands of a DNA molecule. (C)
The answer is not A, as the two DNA strands are already in the double helix. The answer is not B, as the enzyme responsible for copying the DNA sequence is DNA polymerase, not RNA polymerase. The answer also cannot be D, because although short RNA primers are involved in DNA replication, this does not occur at the origin of replication.
