An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.

Alex787 [66]

The statement that enzymes need to be produced by cells in large quantities because they are consumed by the chemical reactions in which they participate is False.

<h3>How much quantity of enzyme is needed in a Chemical Reaction?</h3>
  • Between 1 and 10,000 substrate molecules can be catalyzed by an enzyme every second.
  • Due to the fact that they do not change throughout reactions, enzymes are only found in trace levels in cells. and they have a strong affinity for their substrate.
  • By lowering the activation energy and activating more molecules, they act as the catalyst to make the process easier to happen. Because the enzyme must react with the substrate, the concentration of the enzyme is crucial in chemical reactions.
  • When enzymes locate their intended substrate, they seize them, undergo a transformation, and then move on to the subsequent substrate molecule.
