Which RNA picks up specific amino acid from the amino acid pool in the cytoplasm to the ribosome during protein synthesis?
1 t-RNA
2 m-RNA
3 r-RNA
4 Sn-RNA
5 hn-RNA
Explanation:
t-RNA carries amino acid in the amino acid acceptor arm and read codon of mRNA by the anticodon arm. - It brings specific amino acid and add them to the polypeptide chain. - The t-RNA picks up specific amino acid from the cytoplasm to ribosome during protein synthesis. - m-RNA is formed by the process of transcription using DNA as the template. - r-RNA is the structural component of ribosome and catalytic in function. Help in translation. - hn RNA is present in nucleus, which has larger molecules and act as precursor of m- RNA.

Identify the wrong statement about RNA
1 RNA was the first genetic material to evolve in the living systems.
2 Apart from being a genetic material, it is also a catalyst.
3 DNA evolved from RNA with chemical modifications.
4 RNA being a catalyst is non-reactive and stable
5 Essential life processes like metabolism, translation, splicing involves RNA.
Explanation:
RNA was the first genetic material to evolve in the living system. - A part from being a genetic material it is also a catalyst. - DNA evolved from RNA with chemical modification. - RNA being a catalyst is reactive and hence it is unstable. - They are essential life processes like metabolism, translation, splicing involves RNA.

Identify the wrong statement
1 In prokaryotes, the structural gene is polycistronic
2 In eukaryotes, structural genes have interrupted coding sequences.
3 Eukaryotes have split gene arrangement.
4 Regulatory sequences do not code for any protein.
5 Intervening sequences appear in mature RNA.
Explanation:
. In prokaryotes the structural gene is polycistronic. - In eukaryotes structural gene have interrupted coding sequence. - Eukaryotes have split gene arrangement. Split gene \(=\) Exons + introns. - Mature RNA is spliced and processed RNA and is involved in protein synthesis. Mature m-RNA contains only exons. - Intervening sequence do not code for any protein.
