1 Set of hunches. 2  If a theory is a set of hunches, it means we arenât yet sure we have the answer. 3  Theories always involve an element of speculation or conjecture. 4  A theory is not just one inspired thought or an isolated idea.  A theory offers some sort of explanation.
Uracil is paired with thymine in RNA and it is paired with Adenine in DNA. In DNA transcription (from DNA to RNA), uracil pairs with adenine. in regular DNA replication adenine pairs with thymine.
Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil. They are abbreviated (A, C, G, T, U). Three of the bases (A, G, C) are found in both DNA and RNA. However, uracil (U) is found only in RNA and thymine (T) is found only in DNA.he first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine.
