Using the lab opening as an example explain how genes are activated in the presence of lactose. what occurs when genes are activated why is the lac oberon activated make sure to use the following words in your answer proteins operator tepressor

Operon is the set of genes that are present together and occurs in prokaryotes like bacteria. Control of operons is significant.

Explanation:

Production of RNA and protein requires energy. Cells can't stand to squander energy making genes in the event that they needn't bother with them. Therefore, operons, for example, the lac operon must turn on when the metabolism of lactose is required and turn off when it isn't required.

The lac operon is for the metabolism of the lactose. Typically, the lac operon remains off. A repressor protein ties the operator or control region upstream of the operon anticipating translation. At the point when lactose is available outside the cell, it crosses the cell layer and goes about as an inducer of the operon.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
