rRNA & tRNA

Transfer RNA (tRNA) -

In eukaryotic rRNA and tRNA synthesis is catalysed by :

Write functions of mRNA, tRNA and rRNA.

Assertion : All three ENAs (mRNA, tRNA and rRNA) are needed to synthesise a protein in a cell. Reason : The mRNA provides the template, RNA brings aminoacids and reads the genetic code, and tRNA play structural and catalytic role.

tRNA, SsrRNA, snRNAs are transcribed by:

Differentiate between mRNA and tRNA.

Which of the following factor is required for the protein synthesis? 1. Initiation codon 2. GTP and ATP 3. Peptidyl transferase 4. tRNA 5. mRNA 6. Amino acid activating enzyme 7. rRNA Choose the correct combination.
