Fill in the left, with the numbers on the right as the options

im isolated a second microorganism, this time from inside a burrow and decided to take a closer look at the genome of the organism. Assuming he was correct in identifying it as a bacteria (Bct2), he could make some further assumptions about how its genes are arranged. Match the statement with the most appropriate answer. a group of prokaryotic genes that are transcribed 1. the lac operon together 2. monosaccharide a single mRNA that encodes multiple proteins 3. a promoter 2 region that binds the repressor 4 5. a repressible operon ei.. 7. an operator an example of an inducible operon polyunsaturated polycistronic an operon a repressor 9. 10 monocistronic

Explanation / Answer

8. Operon. It is an functional unit of DNA that carries structural genes and it's regulatory sequences( enhancer and operator) under control of a single promoter.

7. Polycistronic. This is very common in bacteria where promoter and terminator sequence is common for all structural genes.

4. An operator. It has affinity for repressor protein. They are biparted and has palindromic sequence. Binds with repressor atleast in dimer form.

1. Lac operon. Allolactose is the inducer of lac operon which controls it negatively.
