Explanation: ++there are always equal no. of guanine and cytosine nucleotides in a molecule. ++they only pair with each other due to their chemical nature..

What is Chargaffs law?

Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.)

How many nitrogenous bases are there in DNA?

four
Understanding DNA replication Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).

Are there always going to be an equal number of guanine and cytosine in a DNA molecule How about adenine and thymine Why?

Adenine always binds with thymine, and cytosine always binds with guanine. Since certain bases always appear in pairs, they will have equal percentages of the DNA composition. The percentage of adenine will equal the percentage of thymine, and the percentage of cytosine will equal the percentage of guanine.

Are there always going to be an equal number of adenine and guanine nucleotides in a molecule?

Are there always going to be an equal number of adenine and thymine nucleotides in a molecule? Are there always going to be an EQUAL number of guanine and cytosine molecules in a molecule of DNA? Yes, because guanine can only pair with cytosine, according to Chargaff’s Rule.

Is there always going to be an equal number of adenine?

The answer to this question is “yes”. The total number of adenine molecules or their pair is same with that of the number of thymine nucleotide in molecules.

Do purines equal pyrimidines?

Rule 1. Chargaff determined that in DNA, the amount of one base, a purine, always approximately equals the amount of a particular second base, a pyrimidine.

Q36. Yes, adenine can only pair with thymine because of their chemical structures.Q37. Yes, guanine can only pair with cytosine because of their chemical structures.
