List the three main types of rna and explain what they do seqs

There are three main types of RNA:

1. messenger RNA (mRNA) which carries the genetic information transcribed from DNA.

2. transfer RNA (tRNA) which binds and carries amino acids to the growing end of a polypeptide based on the mRNA sequence.

3. ribosomal RNA (rRNA) which together with proteins forms ribosomes and catalyze the assembly of amino acids in the polypeptide.
