- Which of the following statements are true regarding the properties of DNA and RNA polymerase. Select all that apply. Both DNA and RNA polymerase synthesize nucleic acid strands in the 5" to 3' direction. Both DNA and RNA polymerase can initiate strand synthesis on their own. I. RNA polymerase initiates strand synthesis, while DNA polymerase depends upon an existing strand to continue synthesis. II. RNA polymerase only uses ribonucleotides for strand synthesis. DNA polymerase only uses deoxyribonucleotides for strand synthesis. V. Au DNA and RNA polymerases from eukaryotes behave very differently from DNA and RNA polymerases found in prokaryotes. O VI.arrow_forwardIf the following piece of the partially double stranded DNA: 5' ATCG 3' 3' TAGCGGCATCCG 5' and add DNA polymerase, dTTP,dGTP and dCTP, what will be the sequence of the nucleotides that will be added?

(type 1, 2 or 3 in the blank) conservative model semi-conservative model dispersive model The model that best describes DNA replication essentially means the DNA is kept intact and a copy is made by enzymes the DNA is separated and a new daughter copy is paired to each parental strand the DNA is dispersed into small nucleotide segments and copied pieces are inserted into the gapsarrow_forward
- The following diagram represents a DNA molecule that is undergoing replication. Draw in the strands of newly synthesized DNA and identify (a) the polarity of the newly synthesized strands, (b) the leading and lagging strands, (c) Okazaki fragments, and (d) RNA primers. Origin 3' 5' 5' 3' Unwindirg Unwinding Originarrow_forwardWhich of the following statements regarding the fidelity of DNA replication is true? DNA polymerase has a 3'-5' exonuclease activity that removes incorrectly paired nucleotides. The DNA polymerase active site is highly flexible and can easily 'fit' incorrectly paired incorporated nucleotides. I. DNA polymerase never makes an error in the nucleotide being incorporated. The stability of base pairing is not a factor in controlling the fidelity of nucleotide incorporation during replication. IV. DNA polymerase has evolved to make errors at a relatively high rate because this is what drives evolution. OV.arrow_forwardHow does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.arrow_forward
