Question

Of the following functions, the major purpose of RNA is to A) function in the synthesis of protein. B) transmit genetic information to offspring. C) make a copy of itself, thus ensuring genetic continuity. D)form the genes of higher organisms. E) act as a pattern or blueprint to form DNA.

Answer 1

The primary role of RNA is in protein synthesis. The DNA code is transcribed into mRNA; which then interacts with rRNA in ribosomes, while tRNA brings required amino acids. The proteins are then assembled according to the mRNA's code.

Step-by-step explanation:

The major purpose of RNA (Ribonucleic Acid) is to function in the synthesis of protein. This is accomplished through the coordinated functions of its different types, which include messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), and microRNA (miRNA).

The DNA code is first transcribed into an mRNA molecule. This molecule is, in essence, a 'message' from the DNA, carrying the information needed to create a specific protein. In the cytoplasm, the mRNA interacts with rRNA which part of the ribosomes, the sites of protein synthesis. The tRNA brings the necessary amino acids to these ribosomes, where they are assembled into a protein based on the code provided by the mRNA.

Therefore, RNA primarily functions to ensure the accurate translation of DNA's genetic code into the proteins necessary for the cell's functions.
