Because it doesn't contain the same triplet as DNA well most of the times yes but sometimes no where there is thymine involved for example if the gene of the DNA coding for a specific polypeptide has the first triple as ATG then tRNA will be AUG as there is no thymine In tRNA9700/12/m/j/12
21. Which statements about tRNA structure are correct?
1. There is a binding site for the attachment of a specific amino acid, as well as a different binding site for the attachment to the ribosome, in order to allow translation to occur.
2. There is a ribose-phosphate backbone with strong covalent phosphodiester bonds and areas within the polynucleotide chain where base-pairing by hydrogen bonding occurs.
3. There is a section known as an anticodon that contains the same triplet of bases as the triplet of DNA bases that has been transcribed to produce the mRNA codon.
A. 1 only
B. 1 and 2 only
C. 2 and 3 only
D. 1, 2 and 3
The answer given is B. Can anyone explain why the third statement is incorrect?
Thank you in advance
