Choose the correct answer from the alternatives given : Which of the following statements is correct regarding ribosomes?

AMost of a cells DNA molecule are stored there.
BComplete polypeptide is released from there.
Correct Answer
CmRNAs are produced there.
DDNA replication takes place there.

Solution

Ribosomes are, called as protein factories. Each ribosome has two unequal parts, small and large. The larger subunit of the ribosome has a groove for pushing out the newly formed polypeptide and protecting the same from cellular enzymes. The smaller subunit fits over the larger one like a cap but leaves a tunnel for mRNA. The two subunits come together only at the time of protein formation.
So, the correct answer is 'Complete polypeptide is released from there.'
