Final answer:
The claim that eukaryotic cells use polymerase I to remove RNA primers is false. RNase H is responsible for removing RNA primers in eukaryotic DNA replication, while DNA polymerase I removes primers in prokaryotes. Eukaryotic cells use RNA polymerase I for rRNA synthesis, not for primer removal.
Step-by-step explanation:
The statement that eukaryotic cells use polymerase I to remove RNA primers is false. In eukaryotic DNA replication, RNA primers are removed by the enzyme RNase H, not polymerase I. It is important to note that, during DNA replication, DNA polymerase I is involved in primer removal in prokaryotes, such as E. coli.
Eukaryotic DNA replication is marked by the involvement of multiple DNA polymerases with specific functions. For instance, in addition to RNA primer removal by RNase H, DNA polymerase δ (delta) and DNA polymerase ε (epsilon) are responsible for the elongation of the new DNA strands. This complexity reflects the sophisticated organization and regulation of eukaryotic cells.
In contrast, RNA polymerase I is primarily involved in the synthesis of ribosomal RNA (rRNA) in eukaryotic cells. It initiates transcription at a promoter sequence and aids in the elongation of the rRNA transcript, which is a separate function from the replication process involving DNA polymerases.
