DNA & RNA

• There are three types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
• Nucleic acids can be classified into two main types based on their chemical composition: Ribonucleic Acid (RNA) and Deoxyribonucleic Acid (DNA).
• RNA is single-stranded while DNA is double-stranded.
• Both DNA and RNA are polynucleotides made up of monomer units called nucleotides.
