Identify the correct statement.
1 Capping of hn RNA means the addition of adenylate residues at 5' end hn RNA
2 y gene of lac operon encodes transacetylase enzyme.
3 In Eukaryotes structural genes are interrupted by coding sequences.
4 The lac operon has two regulatory genes and three structural genes.
Explanation:
The structure of eukaryotic genes most eukaryotic genes conations segments of coding sequences (exons). Y-genes lac operon encodes lac permease enzymes.

When Escherichia coli cells are cultured in a medium where Lactose is absent, the ' \(i\) ' gene of Lac Operon continues to produce repressor mRNA, because it is .
1 a non-coding gene,
2 an operator gene,
3 a constitutive gene.
4 a structural gene.
Explanation:
When Escherichia coli cells are cultured in a medium where Lactose is absent, the ' \(\mathrm{i}\) ' gene of Lac operon it is a continues to produce repressor mRNA, because it is a constitutive gene. Lac operon was proposed by Jacob and Monod in E. coli.

In operon concept, regulator gene functions as:
1 repressor
2 regulator
3 inhibitor
4 initiator
Explanation:
In operon concept produces a repressor protein that binds to the operator and thus inhibits the transcription of structural genes the regulator gene acts as a repressor.
