Ivy · Answer 1

uracil, adenine, cytosine

Explanation:

The anticodon of tRNA binds to the triplet codon of mRNA. Adenine of tRNA would pair with uracil of mRNA codon. Uracil of the tRNA anticodon would pair with adenine of the mRNA codon. Similarly, the guanine of the tRNA anticodon binds to the cytosine of the mRNA codon. The codons of mRNA are read from 5' to the 3' direction. And the polarity of the anticodon of tRNA is opposite to that of the mRNA codons. Therefore, if a tRNA anticodon has a sequence of "Adenine, Uracil, Guanine", it would pair with the mRNA codon with a sequence "uracil, adenine, cytosine".

Answer:Uracil, Adenine, Guanine

Explanation: we have two nitrogenous base in both DNA and RNA this includes purine and pyrimidine.

Purine includes-Adenine and Thyamine or Uracil as in case of RNA while pyrimidine includes cytosine and guanine. Purine base pairs with pyrimidine base in both RNA and DNA i. e

Adenine-Thyamine/Uracil

Cytosine - Guanine.

For this question the pairing includes,

Adenine-Uracil (RNA)

Uracil-Adenine

Cytosine-Guanine
