In bacteria, catalytic $RNA$ is found in
$60S$ subunit of ribosome
$50S$ subunit of ribosome
$30S$ subunit of ribosome

Length of $DNA$ in $E$. coli is
Chromosomes of all races of human are
The frequency of a mutant gene in a population is expected to increase, if the gene is
$A$ : Wobbling reduces the number of $tRNAs$ required for polypeptide synthesis.
$R$ : It increases the effect of code degeneracy
The structure present over chromosome is
