Current Question (ID: 12721)

Question:

Select which one is not true for ribosome

Options:

1. Made up of two sub-units
2. Form polysome
3. May attach to mRNA
4. Have no role in protein synthesis

Solution:

Ribosomes are truly called as protein factory and they play a vital role in proteins synthesis. Thus, the statement that ribosomes have no role in protein synthesis is not true. Other statements are true for ribosome. Ribosomes are made up of two subunits, i.e., large and small. In prokaryotes it is 70S (50S and 30S). In eukaryotes it is 80S (60S and 40S). Polyribosomes. Several ribosomes attach to a single mRNA and form a chainlike structure. Polysomes. They are formed by the attachment of ribosomes with mRNA.
