[A]: DNA code is copied in the synthesis of m-RNA.
[R]: tRNA moves out of the nucleus and after attaching on ribosomes form the template

A

If both A and R are true and R is the correct explanation of A.

B

If both A and R are true but R is not the correct explanation of A.

C

If A is true but R is false

D

A is false but R is true.

Text Solution

Verified by Experts

The correct Answer is:
C
tRNA is synthesized in the nucleus as a DNA template. Only 0.025% of DNA codes of tRNA . tRNA is an exception to other cellular RNAs in that a part of its ribonucleotide sequence (-CCA) is added after it comes off the DNA template tRNA is formed from only a small part of DNA molecules. Therefore, is does not show any obvious base relationship to DNA.

The following features occur during protein synthesis: (i) Movement of m-RNA from the nucleus into the Cytoplasm, where it binds to the ribosomes (ii) Formation of amino acyl t-RNA complex (iii) Transcription of specific segments of DNA into m-RNA molecules in the nucleus (iv) Binding of N-terminal amino acid, methionine t-RNA to the 'P' site of the ribosome.
