What background information did Watson and Crick have made available for developing a model of DNA? What was their contribution?
Answers (1)
Watson and Crick made the following background Information available for developing a model of DNA:
• Pairing between the two strands of polynucleotide chains.
• Base pairing of polynucleotide chains is complementary.
• If the base sequence of one strand is known, then the base sequence of another strand can be predicted.
• If each strand from a DNA acts like a template, then both the daughter DNAs would be similar to the mother DNA.
Contributions of Watson and Crick:
• A simple model of DNA was available because of them.
• Genetic implications of DNA replication could be easily understood.
• The model brought a revolution in the understanding of biology at a molecular level.
