QUESTION 13 Which of the following components of the RNA is/are important for the binding specificity of the tRNA synthetase? A. acceptor stem OB. anticodon loop Ос. Twc lоор O D.A and B E. A, B, and C QUESTION 14 Proteins are synthesized starting with the 5' end O alanine O the amino terminus the carboxy terminus

Answer 1

Aufswere Question 1997- Here option DY A and is the covereet choice for this question that means - acceptor stem and anticodon Poop is important for the binding specificity of the ARNA Gyothalabe.. Question 14:~ Answer: Proteins are synthesized starting with athe Se amino ferminus. Here the amino terminus also be connect answer fout of we talk about protein Bynthesis we know that all mRNA are read in the 5' to 3' direction for translation and polypeptide chains are Cynthesized from the amino to carboxy fereménues. . Explanation! ~ It is true s'end is the Starting point for protein synthesis but .. Protein Poynthesis can not be start renfil the AUG codon one start codon is reached ore attached. nae Acers cocon can not stort the transiation. That's why amîno terminus in connect answer. Explanation of question 13 in the basic mechanism of parstein Bynthesis are also Game in all celts, Pranslation is carried out on mbosomes. ERAA Gerving as and adaptors between mRNA template and amino acid being incorporated into protein. opraptor function of the ARNA invoines

two Beparated regious of the molecule, AXI FRACA have the sequence cch at their 31 terminus. and amino acids are covalently attacked to the ribose of the terminal adenosine. The mRNA sodon template is recognized by the anticodon. Loop located at the other end of forded truth and finds to appasopaniate codon by complementary base paining Recognition of correct tRNA by the amnüroacyl ERNA Synthetase is highly Gelechwe Because Synthetase recognizes specific nucleotide sequences. & the acceptor stem is the site of attachment of amino acid to transfer RNA CERDA). The acceptor branch usually forms a regular Artype double to helix, with the four single stranded nucleotides extending in a regular belical continuity. & Anticodon loopa pairs with a mRAA specifying contain amino acid. Thats why acceptor stem and anticodon loop is important for Finding specificity of t-RNA Figut hatase. the clover-leaf fornis an L-shaped tertiary structure with acceptor arm at one end and anticodon armat of her end.
