Final answer:
DNA polymerases, RNA polymerases, and transcription factors are directly involved in DNA replication and transcription. Histones and lamins are not directly involved in the polymerization process but play roles in DNA packing and nuclear structure, respectively.
Step-by-step explanation:
The components involved in DNA replication and transcription include DNA polymerases, RNA polymerases, and transcription factors (TFs). DNA polymerases are crucial for adding nucleotides to the growing DNA strand during replication. RNA polymerases are necessary for synthesizing RNA during transcription. Transcription factors are proteins that help in the initiation of transcription by enabling the binding of RNA polymerase to the DNA. While histones are associated with the packing of DNA and can influence these processes indirectly, they are not directly involved in the polymerization of nucleic acids. Lamins play a role in the structure of the nuclear envelope and do not have a direct role in replication or transcription.
