First to answer with a correct answer gets it is hard to believe, but the desert and the tundra have a lot in common! the most obvious is that both biomes have little available water. what plant adaptations would you expect to see in these two biomes? include four adaptations you might see in both biomes.

You would expect plants to have leaves with little surface area, and develop a different form of carbon storage during photosynthesis that better suits these environments like CAM or C4. They would also have thick cuticles to prevent water loss. Plants in the tundra and the desert generally adapt by growing as low-lying shrubs.

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.
