Final answer:
Chemically modified bases are indeed found on tRNA molecules. When a tRNA is modified, it still recognizes the codon in mRNA that matches its anticodon. These modifications are significant for tRNA function during protein synthesis.
Step-by-step explanation:
Are chemically modified bases found on tRNA molecules? Yes, chemically modified bases are found on tRNA molecules.
41. A tRNA is chemically modified so that the amino acid bound is different than the one specified by its anticodon. Which codon in the mRNA would the tRNA recognize: the one specified by its anticodon or the one that matches the modified amino acid it carries? a. The anticodon will match the codon in mRNA.
12. A nucleic acid is purified from a mixture. The molecules are relatively small, contain uracil, and most are covalently bound to an amino acid. Which of the following was purified? D. tRNA.
tRNA primary transcripts are processed by trimming, enzymatic addition of -C-C-A base triplet at the 3' end, the modification of bases internal to the molecule. This is essential for the proper functioning of tRNA during protein synthesis.
11. The name of the three-base sequence in the mRNA that binds to a tRNA molecule is known as the codon.
2. Transfer RNA (tRNA) is an adapter molecule essential during protein synthesis. It reads the information encoded in the mRNA and transfers the appropriate amino acid to the growing polypeptide chain.
13. The type of RNA known for its catalytic abilities is C. rRNA.
