Question

Host cells containing recombinant DNA can be selected on the basis of the properties of the?

1) vector
2) ribosomes
3) enzymes
4) virus

Answer 1

Host cells containing recombinant DNA can be selected based on the properties of the vector, which is a DNA molecule into which the target DNA is introduced. The selection process involves growing transformed bacteria and using methods like lacZ and antibiotic resistance genes.

Step-by-step explanation:

The properties of the vector are used to select host cells containing recombinant DNA. A vector is a DNA molecule into which the target DNA is introduced to create recombinant DNA. Different types of vectors can be used to clone fragments of foreign DNA and propagate them in a suitable host, such as bacteria. The selection process involves growing transformed bacteria to ensure they contain the recombinant DNA, using methods like lacZ and antibiotic resistance genes.
