What's the difference between mrna and trna, and what are their functions?

MRNA
-messenger RNA
-mRNA is translated into protein at a cellular structure known as the ribosome. A second type of RNA helps form the structure of a ribosome. This type of RNA is called ribosomal RNA, or rRNA
-created from DNA

tRNA
-Transfer RNA
- these molecules molecules ferry amino acids to the ribosome for this assembly
