A life-form from another universe is found to have nucleic acid which includes six different bases - R,S,T,X,Y and Z. The percen
nalin [4]

R, S, and T always have the same percentage composition, while X, Y, and Z always have the same percentage composition. Chargaff's rule is then a viable theory that can be used in this situation.

  • The DNA of any species of any organism must have a 1:1 stoichiometric ratio of the purine and pyrimidine nucleotides, according to Chargaff's principles.
  • More specifically, the ratio of guanine and adenine to cytosine and thymine must be the same. This pattern is present in both the strands of the DNA.
  • The formula comes as A + G = T + C = 1
  • In this universe there are six base pairs R,S,T,X,Y and Z. composition of R,S and T is always same thus these can be considered the purines.
  • The percentage composition of X,Y and Z is always the same thus these can be considered the pyrimidines.
  • applying Chargaff's rule to these bases:

R + S + T = X + Y + Z

= 1:1

Thus, the nucleic acid will contain six base pairs where bonds are formed between RX, SY and TZ.

Question- What would happen if earthquake waves were to interact with layers of the Earth?


Answer- Ok this is what really happens. As you may know there are seven tectonic plates on earth. Deep in the layers of earth energy is being build up to create a movement for thease plates. When the plates move it causes earthquakes but the thing is it depends were you are. If youre far from the movement you will get a small earthquake a small earthquake meaning you wouldnt even feel it, but on the other hand if your right by the movement you will get effected. Take calafornia as an example do you wonder why there are so many earthquakes happenening it because calafornia is right on the action! Calafornia is located right at the rigget place of the tectonic plate were the movement is big!


If my answer helped you please mark it as brainliest thank you and have the best day ever!
