Final Answer:
d) RNA Helicase + Transposase, where RNA Helicase unwinds the DNA double helix, and Transposase influences the movement of genetic elements within the genome, both acting as inhibitors of transcription.
Step-by-step explanation:
In transcription, the synthesis of RNA from DNA, inhibitors play a vital role in gene expression regulation. The accurate pairing of inhibitors for transcription is RNA Helicase and Transposase. RNA Helicase unwinds the DNA double helix, exposing a single-stranded template for RNA synthesis. Simultaneously, Transposase, involved in the movement of genetic elements within the genome, can disrupt the normal transcription process by altering the position of transposons or jumping genes. Together, RNA Helicase and Transposase effectively inhibit transcription by interfering with the usual progression of the process.
It's crucial to distinguish these inhibitors from other enzymes involved in DNA and RNA synthesis. RNA Polymerase and DNA Polymerase are not inhibitors of transcription but are enzymes facilitating RNA and DNA synthesis, respectively. Helicase and Ligase primarily participate in DNA replication and repair, not transcription. Ribosomes are integral to translation, the protein synthesis process, and are not inhibitors of transcription. Thus, the accurate identification of RNA Helicase and Transposase as inhibitors highlights their specific roles in disrupting transcription and influencing gene expression.
