FUNCTIONDNA

• Stores genetic

information

• Codes for proteins

RNA

• Carries messages from

DNA to help in protein

synthesis.

3 types of RNA

A. Ribosomal RNA (rRNA) - part of the ribosomes.B. Transfer RNA (tRNA)- transfers each amino acid to

the ribosome to make proteinsC. Messenger RNA (mRNA) – carries code from DNA

out into the cytoplasm.
