A gene whose expression helps to identify transformed cell is known as
1 Selective marker
2 Vector
3 Plasmid
4 Structural gene
Explanation:
Selective markers help to identify the modified genes/cells in the culture. They are often antibiotic resistance genes which help in artificial selection. They help in identifying transformants and selectively allowing their growth where as eliminating non-transformants. - Plasmid is a small, circular DNA molecule found in bacteria. - Vector containing foreign DNA is termed recombinant DNA. - A structural gene codes for any RNA or protein product other than a regulator factor.

In E. Coli, during lactose metabolism repressor binds to : -
1 Regulator gene
2 Operator gene
3 Structural gene
4 Promoter gene
Explanation:
In the lac operon of E. coli due to the activity of regulator gene synthesis of repressor molecules occurs. These repressor molecules get attached to the operator gene and prevents RNA polymerase from transcribing the operon.

A giant rat is formed in the laboratory, what is the reason:
1 Gene mutation
2 Gene synthesis
3 Gene manipulation
4 Gene replication
Explanation:
By gene manipulation, a giant rat is formed in the laboratory. A giant rat is also known as transgenic rat. - Gene manipulation is the process of altering the genetic makeup of organisms artificially. It is done by inserting, deleting or rearranging genes.

For transformation, micro-particles coated with DNA to be bombarded with gene gun are made up of:
1 Silicon or Platinum
2 Gold or Tungsten
3 Silver or platinum
4 Platinum or zinc
Explanation:
For transformation, micro-particles coated with DNA to be bombarded with gene gun are made up of gold and tungsten. - The gene gun used to bombard the plant cell wall with many DNA coated metal particles by using compressed helium as the propellant. - Gene gun or biolistic particle delivery system is a device used to deliver exogenous DNA, RNA or protein to cell. - Micro carrier particle (gold \& tungsten) used in high velocity micro projectile streams that delivers the coated gene of interest into target gene.
