It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. also catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.
The peripheral nervous system is made up of two systems; the somatic nervous system controls muscle movement and the autonomic nervous system connects with internal organs.

The answer is A. flattened maxilla.
Answer: Acceptor stem and anticodon loop.
Explanation:
Transfer RNA (tRNA) is a small RNA nucleic acid involved in protein synthesis (translation). Each tRNA molecule has two important areas:
- A region of trinucleotides, called the anticodon
- A region where a specific amino acid binds.
<u>During translation, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein</u>. So, in the mRNA chain there are codons, set of three bases, which determine the amino acid to be added to the peptide chain. <u>The tRNA transfers the amino acid</u> to the ribosomes, and then arranges them along the messenger RNA (mRNA) molecule. <u>Then, the tRNA must have an anticodon that is complementary to the codon.</u> Each type of tRNA is specifically combined with 1 of the 20 amino acids to be incorporated into proteins.
This means, during translation, each time an amino acid is added to the growing chain, <u>a tRNA molecule is formed whose base pairs have a complementary sequence with mRNA molecule</u>, ensuring that the appropriate amino acid is inserted into the protein. So, tRNA is a key link between RNA transcription and the translation of that RNA into protein. On the other hand, aminotransferases are enzymes responsible for attaching amino acids to the 3ʹ‐end of cognate tRNAs.
The acceptor stem is the site of attachment of amino acids to tRNA, and anticodon loop is the site of tRNA that is complementary to the codons found in mRNA (that determine the amino acid that will be added) This means, both parts are important for recognition, <u>because the acceptor stem is where the amino acid is, and the anticodon loop ensures that the appropriate amino acid is inserted into the protein</u>.
