Which of these could turgor pressure best be compared to? Group of answer choices

Water pushing a turbine at a hydroelectric plant

Different amounts of water filling a water balloon

Blood moving through the circulatory system

A frozen icicle standing straight upright

Different amounts of water filling a water balloon

Explanation:

Turgor pressure is the force exerted by stored water against a cell wall. In this instance the water is shaping the water balloon and pushing against the rubber which is basically the cell wall of the balloon.

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.
