Amutation of a brown exoskeleton has been introduced into the green beetle population above explain what might happen to the population with the introduction of this new trait

A mutation in the population of green beetle caused the creation of the new trait (brown color), that would make the genes for brown beetles become more frequent in the population. That created difference introduced by mutations might be advantageous and may help an organism survive. For example, green beetles are easier for predators to see and consequently eat than brown beetles. Thus, brown beetles are a little more likely to survive to produce offspring.  

This is an example of how one evolutionary mechanism (mutation) can cause evolutionary change.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
