The study of escherichia coli (e. coli) led researchers to new experimental designs for studying operons. which experimental design did the scientists use?
a. use a microscope to observe cell division to determine the structure of operons.
b. test the response of e. coli to a variety of chemicals to determine the number of operons that are present.
c. insert the operons from one organism into another to determine the mechanism of operon expression.
d. read the genome sequence to determine the quantity and organization of operons.

The correct answer is D. Read the genome sequence which is to determine the organization and quantity of operons.

Operon is termed as the functioning unit of DNA. Operon contains big number of genes which are under control of single promoter.

Genes are being transcribed into strand known as mRNA and then translated into cytoplasm in order to create monocistronic mRNAs whereby they are separately translated.

Prokaryotes is where operons exist. For example, T7 phages is where only two operons are being found.
