Which of the following statements about RNA is true?

RNA, or ribonucleic acid, plays a crucial role in the process of protein synthesis, which is essential for cellular functions and the expression of genes. The central dogma of molecular biology explains that DNA is transcribed into RNA, which is then translated into proteins. This means that RNA acts as a messenger, carrying genetic information from the DNA in the nucleus to the ribosomes, where proteins are synthesized.

The process of protein synthesis occurs in two main stages: transcription and translation. During transcription, a segment of DNA is copied into messenger RNA (mRNA), which then exits the nucleus and facilitates the production of proteins by ribosomes in the cytoplasm. Therefore, it is accurate to say that RNA is directly involved in protein synthesis, making this statement true.
