Step 1: drag the lac promoter to the stretch of dna. do not drag the lacz gene to the dna. what happens? why is this?

RNA polymerase binds to the lac promoter and begins transcribing the stretch of DNA to messenger RNA. Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of the lac promoter 'signals' where the RNA polymerase will bind and where transcription will begin. Promoters are found upstream of a gene to be transcribed.

If a Lac promotor drag to a stretch DNA the genes will replicate that present downstream of the promotor. It is because of Lac promotor is activated by Lactose.

Lac Operon:

In Lac operon, multiple genes are controlled by the single promotor. It is consists of an operator, promotor, and structural genes.

If lac promotor drag to a DNA stretch,

Therefore, if a Lac promotor drag to a stretch DNA the genes will replicate present in the downstream of the promotor.

mendel's first law states that during the formation of reproductive cells , pairs of hereditary factors for a specific trait separate so that offspring receive one factor from each parent.
