Contribution of chargaff
Different species have different amount of bases
In 1949 chargaff discovered that the proportions of bases in DNA depend on the Species The DNA comes from
Phoebe levene the most respected worker in the field , had wrongly insisted that the proportion of DNA bases did not vary from species to species
Chargaff said the number of possible arrangements of bases was truly enormous and therefore DNA could very well be the agent of inheritance
Fixed ratios of bases
Chargaff discovered that in DNA from any source the amount of T was equal to A and also the amount of C is equal to G.
- In any species the ratio of A:T is 1:1 and G:C is 1:1
- Other ratios such as A:G for example varies from species to species
