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.
There are three main types of RNA: 1. mRNA or messenger RNA is the RNA produced by the transcription of DNA leading and lagging strands by DNA polymerase.mRNA is then translated into proteins by ribosomes.he genetic code is read from a type of RNA called messenger RNA (mRNA). Each nucleotide triplet, called a codon, can be read and translated into an amino acid to be incorporated into a protein being synthesized. The genetic code is shown in Figure 7.
