1 Introns are present in mRNA and exons are present in tRNA.
2 Codons are present in mRNA and anticodons in tRNA.
3 Every intron is a set of three terminator codons.
4 Exons are present in eukaryotes while introns are present in prokaryotes.
Explanation:
The mRNA encodes a protein as a series of contiguous codons, each of which is recognized by a particular tRNA. One end of the tRNA matches the genetic code in a three nucleotide sequence called the anticodon.

Identify the correct statement
1 Splicing represent the dominance of RNA world
2 The presence of exons is reminiscent of antiquity
3 Split gene arrangments represent an ancient feature of the genome
4 1 & 3, both are correct.
Explanation:
The presence of exons is reminiscent of antiquity, this is a wrong statement. It can be corrected as the presence of introns is reminiscent of antiquity.

Assertion : hnRNA is smaller than mRNA. Reason : hnRNA is made up of only introns.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Heterogeneous nuclear RNA (hnRNA) is larger than mRNA, because hnRNA is made up of exons and introns and during post transcriptional modifications introns are specificaaly removed by splicing process, hence mRNA becomes smaller than hnRNA.
