Question

which of these nitrogenous base compositions in dna describe chargaffs rules? select all that apply. the dna of all members of a species has the same nitrogenous base composition. the percentage of a is always almost equal to the percentage of t, and the percentage of g is always almost equal to the percentage of c. the percentage of a is always almost equal to the percentage of g, and the percentage of t is always almost equal to the percentage of c. for every adenine in a double - stranded dna molecule, there has to be exactly one thymine.

Explanation:

Las reglas de Chargaff establecen que en el ADN doble - enlace, la cantidad de adenina (A) es igual a la cantidad de timina (T), y la cantidad de guanina (G) es igual a la cantidad de citosina (C). Además, esta relación se mantiene en el ADN de todas las miembros de una especie.

Answer:

• The DNA of all members of a species has the same nitrogenous base composition.
• The percentage of A is always almost equal to the percentage of T, and the percentage of G is always almost equal to the percentage of C.
• For every adenine in a double - stranded DNA molecule, there has to be exactly one thymine.
