The correct option is B P - iii, Q - i, R - iv, S - ii
The tRNA molecule has a clover-leaf-like secondary structure. The amino acid acceptor arm is located at the 3' end of the tRNA molecule. A specific tRNA binds to a specific amino acid through its acceptor stem.
Ꞵ - galactosidase is one of the enzyme produced in lac operon by a structural gene z and help in digestion of lactose.
The genetic code is unambiguous which means each codon specifies one amino acid only.
The process of DNA replication leads to the formation of a continuous i.e.leading strand, and a discontinuous i.e.lagging strand. The fragments of the discontinuous strand are called Okazaki fragments which are joined by DNA ligase, to form a single strand.
Hence, the correct match is-
