Match the following columns correctly.

Column $I$	Column $II$
$(a)$ $m-RNA$	$(i)$ Found in ribosomes
$(b)$ $t-RNA$	$(ii)$ Carries information from $DNA$ to the cytoplasm for protein synthesis
$(c)$ $r-RNA$	$(iii)$ Contains $75$ nucleotides
$(d)$ $RNA$	$(iv)$ $A$ polynucleotide chain containing ribose sugar and uracil base,existing in three types

The clover leaf model of $tRNA$ consists of:

The information flow or central dogma of modern biology is:

Consider the following four statements $(a-d)$ and select the option which includes all the correct ones only $:-$
$(a)$ Transcription and translation can be coupled in bacteria.
$(b)$ The split gene arrangements represent the advanced feature of the genome.
$(c)$ The process of splicing represents the dominance of $\text{RNA-}$world.
$(d)$ The presence of introns in split gene is reminiscent of antiquity.

The diagram shows an important concept in the genetic implication of $DNA$. Fill in the blanks $A$ to $C$.
