Types of Nucleic Acid Polymerases — NEET Biology
📚 Practice ConceptDepending upon the chemical nature of the template (DNA or RNA) and the nature of nucleic acids synthesised from it (DNA or RNA), list the types of nucleic acid polymerases.
Which of the following statements regarding the 'RNA World' hypothesis and nucleic acid properties are NOT correct? S1: RNA was the primary genetic material, and crucial life processes like metabolism and translation evolved centered on RNA. S2: DNA developed from RNA through specific chemical modifications, which conferred greater stability. S3: The reactivity of RNA and its single-stranded nature make it a more suitable molecule than DNA for stable, long-term storage of genetic information. S4: The protein synthesis machinery, including translation, is fundamentally structured around the functions of RNA molecules. S5: The presence of a 2'-OH group at every nucleotide in RNA renders it less reactive and more structurally stable compared to DNA.
