The answer is "A fragment of double-stranded DNA usually formed by the binding of a primer".

Here's why:

1. DNA polymerase and RNA polymerase are both enzymes that are crucial for the process of replication in cells. However, they have different requirements for their functioning.

2. DNA polymerase requires a primer, or a short strand of RNA or DNA (usually about 18-22 bases long), that serves as a starting point for DNA synthesis. This primer is usually a fragment of double-stranded DNA formed by the binding of a primer.

3. On the other hand, RNA polymerase does not require a primer to start the synthesis of RNA. Instead, it can initiate RNA synthesis on its own.

4. Therefore, a fragment of double-stranded DNA usually formed by the binding of a primer is needed for DNA polymerase to synthesize DNA, but is not required for RNA polymerase to synthesize RNA.

5. The other options listed - a piece of double stranded RNA, a promoter or cis regulatory sequence, a general transcription factor, and a gene specific transcription regulator - are not specific requirements for DNA polymerase that RNA polymerase does not also require.
