Question

please give me the answer ​

Answer 1

Answer:

Functioning unit of DNA.

Explanation:

In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter. ... In general, expression of prokaryotic operons leads to the generation of polycistronic mRNAs, while eukaryotic operons lead to monocistronic mRNAs.

Answer 2

Operon:

In genetics, an operon is a functioning unit of DNA containing a cluster of genes under the control of a single promoter.

Lac Operon:

“Lac operon is an operon or a group of genes with a single promoter that encode genes for the transport and metabolism of lactose in E.coli and other bacteria.”

Gene regulation in prokaryotes can be explained with the help of the Lac Operon model.

Productivity:

1. It is the process of synthesis of organic compounds/biomass from inorganic matter using sunlight by producers (plants).

2. It traps energy.

3. It builds up biomass from inorganic nutrients.

Decomposition:

1. It is the process of breaking down of a substance/waste biomass into its constituent parts by decomposers (bacteria, fungi).

2. It releases energy.

3. It releases inorganic nutrients from the biomass.
