1.	What background information did Watson and Crick had available with them for developing a model of DNA? What was their own contribution?
Answer» Watson and Crick had the following informations which helped them to develop a model of DNA: i. Chargaff ’s Law suggesting A=T and C G. ii. Wilkins and Franklin’s X-ray diffraction studies on DNA’s physical structure. Based on these information, Watson and crick proposed i. complementary base-pairing of nitrogenous bases ii. semi-conservative mode of replication iii. occurrence of mutation through tautomerism.

Answer»

Watson and Crick had the following informations which helped them to develop a model of DNA:

i. Chargaff ’s Law suggesting A=T and C G.

ii. Wilkins and Franklin’s X-ray diffraction studies on DNA’s physical structure.

Based on these information, Watson and crick proposed

i. complementary base-pairing of nitrogenous bases

ii. semi-conservative mode of replication

iii. occurrence of mutation through tautomerism.
