Biot-111Lecture 4
Types of molecules• Nucleic Acids
– Deoxyribonucleic acid (DNA)• Chromosomal DNA• Mitochondrial DNA (mtDNA, or less popularly, mDNA) • Chloroplast DNA
– Ribonucleic acid (RNA)• Ribosomal RNA (rRNA)• Messenger RNA (mRNA) • Transfer RNA (tRNA)
– Complementary DNA (cDNA) RNA-DNA Hybrid
• Proteins– Structural proteins
• E.g. Membrane proteins
– Functional proteins • E.g. Enzymes
» Helicases
» Transferases
» Proteases
» Nucleases
» Kinases
» Phosphatases etc.
