 A. nastic response

Explanation:

The thigmonasty is a kind of response shown by a plant towards touch and vibration stimuli. It is generally produce in response to changes in plants that occur due to turgor pressure within a cell. The plants generally show this kind of response so as to decrease their surface area so that they can be protected by the grazing herbivores. Also some insectivorous plants like Venus fly trap use it to trap insects when they come in contact of the plant.

On the basis of the above explanation, The leaves of a plant fold inward when touched as a way to defend themselves from potential harm is the example of A. nastic response.

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.
