Guanine-cytosine is one of the nucleotide pairs that would be found in a DNA molecule. The other is Adenine- Thiamine.
Explanation:
Pyrine bases – Adenine & Guanine- pair with pyrimidines bases – Cytosine and Thiamine. Adenine pairs with Thiamine while Cytosine pairs with Guanine.
In RNA, however, while this same principle of base pairing is observed, rather than Thinmaine, RNA has Uracil in its place. Therefore, in RNA, Adenine pairs with Uracil. There is no Thiamine in RNA.

Answer is: <span>nondisjunction.
</span>Nondisjunction<span> is the failure of </span>homologous chromosomes<span> to separate correctly during </span>cell division, because of tha daughter cells have abnormal chromosome numbers. This example is <span>failure of a pair of </span>homologous chromosomes<span> to separate in </span><span>meiosis I.</span>
Meiosis produce variations in daughter cells whereas mitosis produce identical nuclei.
Hope this helps!
