Give scientific reasons : It is essential that $ tRNA$ binds to both amino acids and $mRNA$ codon during
protein synthesis.
It is essential that $tRNA$ binds to both amino acids and $mRNA$ codon because $tRNA$ acts as an adapter molecule with picks up a specific activated amino acid from the cytoplasm and transferred it to the ribosomal in the cytoplasm where proteins are synthesized. It attracts itself to ribosome with the sequence specified by $mRNA$ and finally it transmits its amino acid to new polypeptide chain.
Match List $I$ with List $II$ .
List $I$ | List $II$ |
$A$. Frederick Griffith | $I$. Genetic code |

$D$. Meselson and Stahl | $IV$. Lac operon |
Choose the correct answer from the options given below:
Match the columns.
Column - $I$ | Column - $II$ |
$(a)$ Splicing | $(1)$ Lac Operon |
$(b)$ Okazaki fragments | $(2)$ Lagging strands |
$(c)$ Jacob and Monad | $(3)$ Lactose |

Identify the correct order of organisation ofgenetic material from largest to smallest.
Protein synthesis in an animal cell occurs
$A$ : Polypeptide sequences are dictated by $DNA$ and represented by $mRNA$.
$R$ : Sequence of amino acids in a polypeptide can be predicted by the exact sequence of nucleotides on the $mRNA$ and template $DNA$
