Juan received a class assignment to write about organisms that live in extreme environments. while doing research online, he found an image that showed microbial bodies thriving in hot springs. the organisms lacked a nucleus or defined organelles. which organisms can he possibly find in such conditions? plant-like protists animal-like protists fungus-like protists archaea

The correct answer is archaea which is last choice above. It is because archaea is a microbe in which they have the property of not exhibiting any nucleus or an organelle which they are to be considered more to be a bacteria because of it.

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.
