Answer 1

rRNA ASSEMBLE WITH PROTEIN TO FORM RIBOSOME, mRNA CARRY CODONS AND tRNA BRINGS CORRECT AMINO ACIDS TO RIBOSOME FOR PROTEIN SYNTHESIS. THERE ARE TOTAL 64 CODONS PRESENT AND 61 CODON CODE TO 20 DIFFERENT AMINO ACIDS. THE BIOSYNTHESIS OF PROTEIN FROM RNA CALLED TRANSLATION.

18 The job ok the tRNA to (A) Bring the corre amino aud to he ibosome → Correct opHon LRNA brings the amino aud to the ribasome rotnynthesis 9 p the inishedprotento their proper ocaHon in the cetl Income J- Option → shipping ob binished pmte.ns to ther proper locaionc the ceocurthrough Co -translatona transbort, these transbort are seouence amino auide (C) Termiate the mRNA correct option → Termination mRNA yntheais occurs thvough Sop igna tauor

Trans csibe the Paye -2 onn → Transcription ob gene ocum res RNA poymerase and other erymer (E)Trans te DNA → DNA tron maion not occurs RNA Hence 야 Hon (A) answer U) Bring the correc amino oud to the riborome amino avd1 (I9) Hoto mo There are 64 codons ob which 2 are codonwhich do no+ Hence tot 1Coo code tor amijo ent nature. eode oany arnino aiid
