There are several different forms of RNA, although three key types of RNA (often cited) refer to (i) messenger RNA (or mRNA), (ii) transfer RNA (or t-RNA) and (iii) ribosomal RNA (or rRNA).
mRNA functions primarily as a transfer/relay molecule (for translating genetic information stored within the DNA molecule into protein, via ribosomes). mRNAs also play a crucial role in determining how much of a protein is being expressed in vivo- generally a greater number of mRNA transcripts siginifies an actively-transcribed (and hence actively-expressed) gene. mRNA molecules are generally single-stranded (monocatenary) and short-lived compared to their parental DNA duplex.
tRNAs function as transport molecules (for ferrying amino acids to the ribosome for extension of the nascent polypeptide chain during its synthesis on the ribosome de novo). tRNAs may exhibit a characteristic secondary structure, comprising a fixed number of stem-loop/hairpin structures (bicatenary sites) and an anticodon (for association with the mRNA codon via complementary base pairing during polypeptide synthesis).
rRNA molecules are often complexed with proteins to form the ribosome (or ribozyme) which is responsible for polypeptide synthesis from their mRNA template in vivo.
In addition, other forms of RNA exist - small interfering RNA (siRNA), microRNA, small nuclear RNA (snRNA), etc. RNAs have also been characterized as fundamental in catalysing numerous in vivo reactions (as riboswitches, etc).
The three types of RNA are:mRNA - single stranded, often depicted like a piece of string
tRNA - in 2D representations, has a circular part at the bottom and three self-hydbridizing arms; resembles a four-leaf clover.
rRNA - forms part of ribosomes; appears round and 'blobby'
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 different forms of RNA. There are mainly categorized into three classes which are messenger, transfer and ribosomal and each has a specific role.
The three types of RNA are mRNA, rRNA, and tRNA.
Love is the answer
There are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA). There are other types, such as the transfer-messenger RNA in some bacteria.
The three types of RNA molecules include messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA).
There are different types of genes for encoding three types of RNA. Protein coding genes are transcribed by RNA polymerase II to yield mRNA. Ribosomal RNA (rRNA) are transcribed by RNA polymerase I. Likewise, transfer RNA (tRNA) are transcribed by polymerase III.
There are three primary types of RNA involved in protein synthesis: messenger RNA, transfer RNA and ribosomal RNA. Whereas most types of RNA are the final products of their genes, messenger RNA (mRNA) is an intermediate in the information transfer process

basically there are of three types...mRNA(messenger RNA),rRna(ribosomal RNA) and tRNa(transfer RNA)....there are involved in protein synthesis .u can see how they work as a cascade of events...refer it
mRNA - messenger RNA tRNA - transfer RNA rRNA - ribosomal RNA
Ribosomal RNA is produced from the nucleolus.Ribosomal RNA consists of rRNA and protein.There are three types of RNA's in our body: mRNA, rRNA and tRNA.
