The clover leaf model of $tRNA$ consists of:

Which of the following does not follow the Central Dogma of molecular biology?

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.

Match List-$I$ with List-$II$.

List-$I$	List-$II$
$A$. Alfred Hershey and Martha Chase	$I$. Streptococcus pneumoniae
$B$. Euchromatin	$II$. Densely packed and dark-stained
$C$. Frederick Griffith	$III$. Loosely packed and light-stained
$D$. Heterochromatin	$IV$. $DNA$ as genetic material confirmation

Choose the correct answer from the options given below:

$A$ mutant micro-organism unable to synthesize a compound required for its growth but able to grow if the compound is provided,is known as

Statement-$I$: The split gene arrangements represent probably an ancient feature of the genome.
Statement-$II$: Introns or intervening sequences do not appear in mature or processed $\text{RNA}$.
