Question

Write the two component of the fist artificial recombinant DNA molecules constructed by Cohen and boyer

Answer 1

The two components are 

1. Antibiotic resistance gene

2. Plasmid of  salmonela typhimurium

Answer 2

"Antibiotic resistance gene" and "Plasmid of salmonella typhimurium" are the two component of the "fist artificial recombinant DNA molecules".

Explanation:

• The two genes used by Cohen and Boyer were from two different Escherichia coli strains to create a single molecule of rDNA.  
• These individual component genes were: Tetracycline resistant gene, kanamycin resistant gene, Antibiotic resistance gene and Plasmid of salmonella typhimurium.
• The restriction enzyme which cuts the "double strand at a particular point" is formed by the Recombinant DNA. The similar enzyme is used to "cut a second piece" of DNA.
