Question

Wired Faculty App

The number of RNA molecules in 60S sub- particles of 80S ribosomes are

five

four

three

two

Solution

C.

three

In 80S eukaryotic ribosome, there are two subunits. One large subunit, that is, 60S and one small subunit, that is, 40S.

In animals, 60S subunit is further divided into 28- 29S + 5S + 5.8S and 40S is divided into 18S.

In plants, 60S subunit is divided into 25S +5S +5.8S and 40S subunit is divided into 16- 18S.
