(d) 4
Show Answer
Answer : c
Hints & Solution
(c) Eukaryotes have three types of RNA polymerases : (i) RNA polymerase I - It is found in nucleus and is responsible for rRNA (28S, 18S and 5.8S) synthesis. (ii) RNA polymerase II - It is found in nucleoplasm and is responsible for mRNA synthesis. (iii) RNA polymerase III - It is found in nucleoplasm and is responsible for tRNA and 5S rRNA synthesis.
