Question

Bacterial pre rRNA transcript has ________________

(a) 23S 4S 16S 5S

(b) 16S 4S 23S 5S

(c) 16S 5S 23S

(d) 23S 16S 5S

I had been asked this question by my college professor while I was bunking the class.

This interesting question is from RNA Processing Control in portion Regulating Gene Expression in Eukaryotes of Cytogenetics

Answer 1

Correct option is (b) 16S 4S 23S 5S

For explanation I would say: The pre-rRNA transcript of prokaryotes is 30S, it has 16S 4S 23S and 5S subunits in sequence where the 4S subunit codes for the tRNA.
