Stuttering is a speech disorder characterized by repetition of sounds, syllables, or words; prolongation of sounds; and interruptions in speech known as blocks. An individual who stutters exactly knows what he or she would like to say but has trouble producing a normal flow of speech.
The 3 types of RNA are mRNA is a long strand, the tRNA is shaped  like a clover leaf pattern. The third shape is Ribosomal RNA, it  is a very complex shape.
1 tRNA (transfer RNA) - Type of RNA that delivers amino acids to ribosomes during translation in the order specified by the mRNA. 2  rRNA (ribosomal RNA) - A type of RNA that becomes part of ribosomes.here are different types of RNA, ribosomal RNA, messenger RNA and transfer RNA. Ribosomal RNA (rRNA) is found in ribosomes and in the nucleolus where it is manufactured. messenger RNA (mRNA) can be found in the nucleus when it is translating DNA to mRNA in translation.
