Which statement below is false? The weakness of hydrogen bonds between the bases of DNA allows base pairs to separate during both DNA
replication and protein synthesis.
Today, scientists use 2-D, 3-D, and virtual models to represent the structure of DNA.
Nucleotides are connected by covalently bonded sugar and phosphate molecules.
O Studies of the amounts of each DNA base in different organisms led to the concept of complementary base-
paring
Experiments conducted were able to demonstrate that'RNA was the genetic material that passed on
information to the next generation.
O Modern advances have added to our understanding of the structure of DNA and its function.

explanation:

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.

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
