DNA Math Practice

Master DNA math with practice on Chargaff's Rule and base calculations!

Chargaff's Rule Use the information in the video to help solve the practice problems below. For the following questions, state how many DNA bases are present. There are 500 total bases in a specific DNA molecule. Of the 500 bases, 100 are A’s. That means that there are 100 T's, 150 C's and 150 G's. There are 500 total bases in a specific DNA molecule. Of the 500 bases, 150 are A’s. That means there are 150 T's, 100 C's and 100 G's. For the following questions, state what percentage of DNA bases are present. There are 500 total bases in a specific DNA molecule. Of the 500 bases, 15% are A’s. That means in the DNA molecule 15% are T's, 35% are C's and 35% are G's. 5. There are 500 total bases in a specific DNA molecule. Of the 500 bases, 20% are G’s. That means in the DNA molecule 20% are C's, 30% are A's and 30% are T's. Explain why the number of bases keep following the same trend (turning out the way they do). Hint: Use the information from your notes, the video above and practice problems above to help you answer this question. Fill in the blank below. If there is an error with the DNA bases and they are not matched properly, it is called a mutation.
