Ribosome Structure

Q. Several ribosomes may attach to single mRNA and form a chain. These ribosomes

Q. The primary job of rRNA in the smaller subunit of ribosome is to

1. Provide some part of the genetic information
2. Facilitate the binding of tRNA to the ribosome
3. Facilitate the binding of mRNA to the ribosome
4. Facilitate the transfer of peptidyl bonds between amino acids

Q. Regarding the assertion and reason, select the correct option.
Assertion $\left[A\right]$: Ribosomes are also known as ribozymes.
Reason $\left[R\right]$: Ribosomes facilitate their binding with the mRNA on their own.

1. A is true but R is false
2. R is true but A is false.
3. Both A and R are true, but R does not explain A
4. Both A and R are true and R explains A
