Hint: RNA stands for ribonucleic acid. RNA is the polymer of ribonucleotides linked together by $3^{1} - 5^{1}$ phosphodiester linkage. Types of RNA in prokaryotic and eukaryotic organisms are messenger RNA (m RNA), transfer RNA (t RNA), ribosomal RNA (r RNA). RNA is one of the two types of nucleic acids located in all cells.
Complete Answer:
Generally, RNA transfers information from the nucleus (DNA) to the cell (proteins) for use. Makes up ribosomes. Helps assemble proteins.
Functions of RNA:
1. mRNA (messenger)- give instructions proteins
2. tRNA (transfer)- carriers that match amino acids to codons during translation
3. rRNA (ribosomal)- part of the ribosomes- ribosomes are RNA plus proteins
4. SnRNA (small nuclear)- part of spliceosomes, that edit mRNAs
5. siRNA’s (small interfering) control gene expression
6. our body needs to make proteins in order to carry out cell function. The instructions on how to make proteins are found in our DNA.
Thus, the option (D) is correct.
Note: Ribosomes stand for ribonucleo- protein particles. Ribosomes serve as workbenches, with mRNA acting as the blueprint in the process of protein synthesis. Types of ribosomes are matrix ribosomes and plasma membrane ribosomes. DNA is a double stranded molecule that is twisted into a helix. Transcription is ribosomes cannot read our DNA, so it must be converted into RNA which our ribosomes can read.
