There are three types of RNA
All are involved in the process of protein synthesis
They are :
tRNA (transfer RNA) - small, single-stranded molecule which forms the clover-leaf shape, with one end of the chain ending in cytosine-cytosine-adenine sequence at which point the amino acid it carries attaches itself. At the opposite end of the chain is a sequence of three bases called the anticodon. tRNA molecules transport amino acids to the ribosome so that the proteins can be synthesised.
mRNA (messenger RNA) - long, single-stranded molecule formed into a helix, maunfactured in the nucleus. It carries the genetic code from the DNA to the ribosomes in the cytoplasm
rRNA (ribosomal RNA) - Large complex molecule made up of both single and double helices, found in the cytoplasm. Ribosomes are made up of rRNA. It is the site of translation of the genetic code.
