Final answer:
RNA acts as a messenger between DNA and protein production, which is a. true. This role is performed by messenger RNA (mRNA) that carries genetic information from DNA to ribosomes during protein synthesis.
Step-by-step explanation:
The statement that RNA is the messenger between DNA and protein production is a. true. During the process of protein synthesis, messenger RNA (mRNA) serves as the intermediary.
The sequence of events in protein synthesis begins with transcription, where the DNA's genetic instructions are transcribed into mRNA within the nucleus.
Afterward, this mRNA exits the nucleus and enters the cytoplasm, where ribosomes read the information inscribed on the mRNA strand during translation.
The ribosomes then use this information to string amino acids together into a protein.
Therefore, mRNA carries the genetic message from the DNA to the ribosome, effectively managing the synthesis of proteins based on this genetic information.
