Homework Answers
I believe the correct answer to be:
Statement 1) True
Statement 2) True
Statement 3) False (DNA are transcribed into mRNA)
Statement 4) False (It is transfer of information, not a conversion)
Statement 5) True

1. Which of the following statements concerning transcription of bacterial mRNA is not true? Bacterial mRNA must have intron material removed before it can be used in the process of protein translation.* Energy necessary for transcription is provided by the breaking of phosphate bonds carried by ribonucleotide triphosphates (rNTPs). A sigma factor recognizes the promoter site sequences on the DNA strand during transcription. A guanine-rich sequence on the template DNA molecule causes the growing RNA strand to loop and detach.

Which of the following statements is correct concerning operon gene control? Positive control requires an activator protein to stimulate transcription of the structural genes within an operon. In negative control, a repressor protein inhibits or turns off transcription of the structural genes within the operon. An inducible operon normally is not transcribed. It requires an inducer molecule to stimulate transcription either by inactivating a repressor protein in a negative inducible operon or by stimulating the activator protein in a positive...

One strand of a section of DNA isolated from E. coli reads: Suppose that an mRNA is transcribed from this DNA using the complementary strand as a template. What will the sequence of the mRNA in this region be? What is the amino acid sequence of the proteins? Would the same proteins be made if the other strand of DNA served as template for transcription? Why or why not? If the T underlined in the above sequence was to go...

Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...
