Guida verificata passo dopo passo1
Understand the central dogma of molecular biology, which describes the flow of genetic information in a cell from DNA to RNA to proteins.
Identify the role of each type of RNA in the process: mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).
Recognize that mRNA is the intermediate molecule that carries the genetic code from DNA to the ribosome, where proteins are synthesized.
Recall that tRNA is involved in bringing amino acids to the ribosome during protein synthesis, and rRNA is a component of the ribosome itself.
Conclude that the correct molecule to fill in the blank in the sequence DNA → ________ → Proteins is mRNA, as it serves as the messenger carrying instructions from DNA to the site of protein synthesis.
