In bacteria, catalytic $RNA$ is found in
$60S$ subunit of ribosome
$50S$ subunit of ribosome
$30S$ subunit of ribosome
$40S$ subunit of ribosome
The genes, which are confined to differential region of $Y$ chromosome only, are called
In recent past human chromosomes have been studied by a technique using specific, often fluorescent dyes, known as
