Fossils give scientists information regarding the living conditions and characteristics of organisms that were found on the earth thousands of years ago. how can scientists use the fossil record to provide evidence that evolution of organisms has occurred over time? a. older fossils are found in deeper layers of undisturbed rock strata. b. fossils of all life-forms can be found in rock layers. c. all fossils were formed at the same time. d. fossils can provide a complete record of human evolution.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

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.
