 During replication, the new DNA strand is synthesized 

 If _______ was nonfunctional, then DNA polymerase could not replicate the 3?-to-5? strand of template DNA. 

 Greater numbers of errors are found in mRNA than in replicated DNA from the same gene sequence, because RNA polymerase. 

 Which statement about the flow of genetic information is true? 

 Which molecular model describes the structure of the DNA molecule? 

 The part of a protein that determines whether translation will continue in the cytosol or at the endoplasmic reticulum is the _______ sequence. 

 Refer to the figure above showing DNA strands. Which letter represents the leading strand? 

 In prokaryotes, the region of DNA to which RNA polymerase binds most tightly is the. 

Order the four steps shown as they would occur, from beginning to end, during expression of a eukaryotic gene.(1) Pre-mRNA is processed to make mRNA.(2) Ribosomes translate the mRNA message to make proteins.(3) mRNA is transported to the cytoplasm.(4) DNA is used as a template to make pre-mRNA.
