They interact with t RNAs and other molecules that are crucial to protein synthesis.In bacteria, the small and large r RNAs contain about 15 nucleotides, respectively, whereas in humans, they have about 18 nucleotides, respectively.

mi RNA can break down m RNA that it is complementary to, with the aid of enzymes.

This can block the m RNA from being translated, or accelerate its degradation.

It carries complimentary genetic code copied, from DNA during transcription, in the form of triplets of nucleotides called codons.

Each codon specifies a particular amino acid, though one amino acid may be coded for by many different codons.

Beyond the primary role of RNA in protein synthesis, several varieties of RNA exist that are involved in post-transcriptional modification, DNA replication, and gene regulation.

Some forms of RNA are only found in particular forms of life, such as in eukaryotes or bacteria.

However, the structure and function of ribosomes is largely similar across all species.

t RNA is the smallest of the 3 types of RNA, possessing around 75-95 nucleotides.

RNA or ribonucleic acid is a polymer of nucleotides that is made up of a ribose sugar, a phosphate, and bases such as adenine, guanine, cytosine, and uracil.

It plays a crucial role in gene expression by acting as the intermediate between the genetic information encoded by DNA and proteins. The key difference in RNA structure is that the ribose sugar in RNA possesses a hydroxyl (-OH) group that is absent in DNA.
