The proportions of the bases are consistent within a species; however they do vary between species. Using the base-pair rules, complete the following table to show the percentage of each type of base in the five different organisms.

Answer:

The correct answer would be:

                  A         G          C         T

Human:   31          19          19       31

Cow:         28         22      22         28

Salmon:     29       21       21         29

Wheat        27      23        23        27

Yeast         31         19       19         31

Explanation:

According to the rule of Chargaff which states or explains the amount of the A, T, G, and C bases in the DNA molecule. It says that the DNA of any organism should have a pyrimidine and purine ratio of 1:1. This means the amount of A would be equal to T and the amount G should be equal to the amount of C.

It also says that the amount of a and G would be equal to the amount of C and T. So on the base of this we can find the missing value in the table:

                    A         G          C         T

Human:   31          19          19       31   (A= T and G=C)

Cow:         28         22      22         28  (A= T and G=C)

Salmon:     29       21       21         29   (A= T and G=C)

Wheat        27      23        23        27 (100 - A+T = G+C)

Yeast         31         19       19         31 (A= T and G=C)

The table will be:

                    A               G                   C                    T

Human        31              19                  19                  31

Cow             28             22                 22                 28

Salmon        29             21                 21                 29

Wheat          27             23                 23                 27

Yeast            31              19                 19                   31      

  • As per the to Chargaff's rule, this same quantity of A, T, G, as well as C bases throughout the DNA molecule is stated and otherwise explained. It states that just about any individual's DNA should get a pyrimidine to purine proportion of 1:1.
  • This shows that the quantity of A might have to equivalent to T, as well as the quantity of G could perhaps equivalent to C. It moreover states that the sum of A as well as G is very much like the sum of C and T.

Thus the above answer is right.
