Detailed explanation-1: -The tRNA anticodon is a sequence of three nucleotides that are the complement of the three nucleotides in the mRNA codon. The function of the anticodon is to help the tRNA find the appropriate amino acid that the mRNA codon specified.
Detailed explanation-2: -Answer and Explanation: If the anticodon on a tRNA is 5’ GUA 3’ the codon is 3’ UAC 5’. The 5’ GUA 3’ anticodon is complementary to the 3’ UAC 5’ codon. the mRNA codon UAC codes for Tyrosine.
Detailed explanation-3: -The amino acid glutamine (Q) is encoded by CAG and CAA trinucleotides. Q-tracts in proteins are typically encoded by mixtures of these two codons while expanded Q-tracts in disease-causing genes are typically composed of long uninterrupted repeats of the CAG trinucleotide only.
