Biochemist Erwin Chargaff was the first to discover that, in DNA, [A]=[T] and [G]=[C]. These equalities are now known as Chargaff's rule. Using Chargaff's rule, determine the percentages of all of the bases in DNA that is 10% thymine.

Respuesta :

Answer:

A [tex]= 10[/tex]%

T [tex]= 10[/tex]%

C [tex]= 40[/tex] %

G [tex]= 40[/tex] %

Explanation:

As per the Charfgaff's rule the amount of complementary bases pairs is never equal to each other .

I.e X % of A-T base pair is not equal to Y% of C-G base pairs.

Along with this, concentration of  A will be equal to concentration of T and concentration of C will be equal to concentration of G

Thus, if thymine i,e "T" in a DNA is equal to [tex]10[/tex] %, then the concentration of "A" would be also [tex]10[/tex] %.

Now, the total concentration of A and T is [tex]20[/tex] %

So the remaining [tex]80[/tex] % will be the combined concentration of C and G

Since the concentration of C and G will be equal, the individual concentration of C is [tex]40[/tex] % and the the individual concentration of G is [tex]40[/tex] %
