Question

Explain the structure of tRNA with the function of each arm

Answer 1

Hi.

here is your answer.

$t \: rna \:$
● T - RNA is a single stranded molecule. About 10 to 20 % of the total cellular RNA is of this type.

● It contains 73 - 93 nucleotides only with the molecular ranging between 23,000 to 30,000 . It show 2 patterns of folding upon the itself.

● THE STRUCTURE OF T - RNA CAN BE EXPLAINED BY 2 MODELS
$hair \: pain \: model \\ \\ clover \: leaf \: model$
● The clover leaf model of t- RNA shows, presence of 3. arms namely DHU arm , middle arm and T ¥C arm . This have loop at their ends as amino aceyl binding loop, anticodon loop & ribosomal loop.respectively.

● t - RNA have G nucleotides at 5' end and CCA nucleotides at 3' end.

● t- RNA is also called s- RNA becoz it can not be easily separated even by ultra centrifugation technique.

● It carries specific type of amino acids at CCA end to the ribosome during protein synthesis.

● It places the required amino acids properly in the sequence and translate the coded message of m.-RNA in terms of amino acids.

Parts of RNA
$codogen \\ \\ codon \\ \\ anticodon$

hope it helps you ☺
