Question

Which enzyme did Severo Ochoa identify as capable of polymerizing RNA with defined sequences in a template-independent manner?

विकल्प

• DNA polymerase

• Polynucleotide phosphorylase

• Ribonuclease

• RNA polymerase

Answer 1

Severo Ochoa discovered that the enzyme polynucleotide phosphorylase could polymerize RNA molecules to form chains with defined and repeated nucleotide sequences. This occurred without requiring a template strand, making it a valuable tool for synthesizing specific RNA sequences that could be used to determine which codons code for which amino acids.
