4 0

Answer:

Explanation:

Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.

Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.

Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

What is an adaptive advantage of recombination between linked genes?
Georgia [21]

Answer:

New allele combinations are acted upon by natural selection.

Explanation:

Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.  

The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.

Thus, the correct answer is new allele combinations are acted upon by natural selection.
