Question: Is there genetic information in RNA?

Ribonucleic acid (RNA) functions in converting genetic information from genes into the amino acid sequences of proteins.
The three universal types of RNA include transfer RNA (tRNA), messenger RNA (mRNA), and ribosomal RNA (rRNA).
Messenger RNA acts to carry genetic sequence information between DNA and ribosomes, directing protein synthesis.
Ribosomal RNA is a major component of the ribosome, and catalyzes peptide bond formation.
Transfer RNA serves as the carrier molecule for amino acids to be used in protein synthesis, and is responsible for decoding the mRNA.
In addition, many other classes of RNA are now known. 
Double-stranded RNA (dsRNA) is RNA with two complementary strands, similar to the DNA found in all cells.
dsRNA forms the genetic material of some viruses (double-stranded RNA viruses).
Double-stranded RNA such as viral RNA or siRNA can trigger RNA interference in eukaryotes, as well as interferon response in vertebrates. 
Noncoding RNA molecules play many essential roles in cells, especially in the many reactions of protein synthesis and RNA processing.
The human genome contains genes encoding 18,400 ncRNAs, including tRNA, ribosomal RNA, microRNA, and other non-coding RNA genes.
One historical misconception regarding the ncRNAs is that they lack critical genetic information or function.
Rather, these ncRNAs are often critical elements in gene regulation and expression.
Noncoding RNA also contributes to epigenetics, transcription, RNA splicing, and the translational machinery.
The role of RNA in genetic regulation and disease offers a new potential level of unexplored genomic complexity. 
A gene is a sequence of DNA that contains genetic information and can influence the phenotype of an organism.
Within a gene, the sequence of bases along a DNA strand defines a messenger RNA sequence, which then defines one or more protein sequences.
The relationship between the nucleotide sequences of genes and the amino-acid sequences of proteins is determined by the rules of translation, known collectively as the genetic code.
The genetic code consists of three-letter 'words' called "codons" formed from a sequence of three nucleotides (e.g.
ACT, CAG, TTT).
In transcription, the codons of a gene are copied into messenger RNA by RNA polymerase.
This RNA copy is then decoded by a ribosome that reads the RNA sequence by base-pairing the messenger RNA to transfer RNA, which carries amino acids.
Since there are 4 bases in 3-letter combinations, there are 64 possible codons (formula_1 combinations).
These encode the twenty standard amino acids, giving most amino acids more than one possible codon.
There are also three 'stop' or 'nonsense' codons signifying the end of the coding region; these are the TAA, TGA and TAG codons. 
The discovery of catalytic RNA (ribozymes) showed that RNA could both encode genetic information (like DNA) and catalyze specific biochemical reactions (like protein enzymes).
This realization led to the RNA World Hypothesis, a proposal that RNA may have played a critical role in prebiotic evolution at a time before the molecules with more specialized functions (DNA and proteins) came to dominate biological information coding and catalysis.
Although it is not possible for us to know the course of prebiotic evolution with any certainty, the presence of functional RNA molecules with common ancestry in all modern-day life forms is a strong argument that RNA was widely present at the time of the last common ancestor.
