Final answer:
The statement indicating that proteins, such as glycoproteins which help viruses attach to host cells, and capsids that form capsomeres, is accurate regarding cell communication and virus structure. The roles of RNA, including various forms like mRNA, rRNA, tRNA, and miRNA, are also critical in cell processes.
Step-by-step explanation:
The microbiologist is explaining cell communication, and the question is asking for an accurate statement regarding this topic. In the context of cells and viruses, it's important to note that proteins, like glycoproteins and capsids, play vital roles. Glycoproteins help the virus attach to the host cell, as stated in the provided information. Capsomeres, made up of capsids, are small protein subunits that make up the viral capsid. The role of RNA, including mRNA, rRNA, tRNA, and miRNA, is also critical in various cellular processes. For example, mRNA serves as a single stranded transcript of DNA, the genetic material found in animal cells is primarily DNA within the nucleus, and RNA is involved in the synthesis of the proteins. Therefore, the key molecules involved in cell communication and virus structure include proteins and RNA.
