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.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C

`**` All three RNAs (mRNA, tRNA and rRNA) are needed to synthesise a protein in a cell.
`**` mRNA function as template, tRNA reads the genetic code and brings aa and rRNA plays structural and catalytic role.

Assertion : There is single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA (mRNA, tRNA and rRNA) in eukaryotes. Reason : In bacteria, there are at least three RNA polymearases are required.

Assertion : Initiation step of protein synthesis in prokaryotes and eukaryotes has several differneces. Reason : They both form mRNA -tRNA complex with smaller subunit of ribosome.

Here are some correct and some wrong statements. Correct only those statements which are wrong: (a) The genetic code is universal. (b) The genetic code is ambiguous. (c) The genetic code is regenerate. (d) Transfer RNA (tRNA) carry amino acids to mRNA codons and used again and again in transcription. (e) UAA, UAG and UGA are terminator codon. (f) Lac operon consists of regulatory genes, operator gene, structural and promoter gene.
