Final answer:
mRNA is transcribed from DNA and then translated by multiple ribosomes via polysomes, leading to the efficient synthesis of proteins. mRNA is not immediately destroyed post-translation to allow for regulation. Thallophytes traditionally include Fungi, Algae, and Lichens.
Step-by-step explanation:
Protein Synthesis and mRNA Replication
During protein synthesis in the cell, mRNA is not replicated; rather, it is transcribed from DNA before translation. Once transcribed, mRNA can be translated by multiple ribosomes simultaneously in a process utilizing polyribosomes or polysomes. These structures increase the efficiency of protein synthesis as they allow for multiple copies of a protein to be synthesized from a single mRNA strand at the same time. After translation, mRNA is not immediately destroyed but can have a short life span, which ensures that proteins are not overproduced when not necessary.
As for Thallophytes, according to some sources about plant divisions, they are comprised of Fungi, Algae, and Lichens. Thallophytes are characterized by a simple undifferentiated thallus structure that lacks true roots, stems, and leaves. This group includes a diverse array of organisms that differ significantly in form and function.
