The dna content for an organism is analyzed. The results showed that 21% of the nucleotides contained the nitrogenous base adeni
Serjik [45]

If the results show that 21% of the nucleotides contain adenine, then the cytosine fraction in vivo is 29% and the thymine fraction is also 21% (options A and C).

<h3>Define double helix model of DNA?</h3>
  1. DNA is a double helix molecule made up of two long strands of nucleotides.
  2. There are four types of nucleotides in DNA, each containing a different nitrogenous base: adenine, guanine, thymine, cytosine.
  3. Adenine always pairs with thymine and guanine pairs with cytosine, according to the base-pairing rules.
  4. As a result, the percentage of adenine equals the percentage of thymine, and the remaining percentage equals guanine + cytosine (29 + 29 = 58 >> 58 + 21 + 21 = 100).
  5. Therefore, if the results show that 21% of the nucleotides contain adenine, then the percentage of cytosine in vivo is 29% and the percentage of thymine is also 21%
