When DNA is copied (replicated), which of the following is NOT true? DNA polymerase adds nucleotides to the 3' end of a growing new strand of DNA. All regions of the DNA are replicated, not just those that are gene regions. DNA polymerase binds at the TATAA site on the coding strand to initiate replication. In any given location, one strand of DNA is copied continuously and the other in fragments

How 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.
Energy that drives the attachment of a nucleotide to the end of a growing strand of DNA comes from ________. a. the nucleotide b. DNA polymerase c. phosphate-group transfers from ATP
DNA replicates by which of the following models? a. conservative b. semiconservative c. dispersive d. none of the above
Why is DNA replication called semiconservative?
Which of the following replication proteins is incorrectly paired with it’s function? DNA polymerase - adds nucleotides to the growing strand Single stranded binding proteins - hold the DNA strands apart while they are being replicated Ligase - enhances separation of DNA strands Topoisomerase - relieves torsional stress due to unwinding by the DNA Primase - synthesizes a short RNA sequence to initiate replication
DNA replication is called semi-conservative because ___ (all, all or none) of the two new strands of DNA is old DNA from the original DNA molecule and ___ (all, all or none) is new DNA.
Which of the following statements BEST describes the process of DNA Replication? Group of answer choices The two strands of the parental molecule separate and serves as template for synthesis of a new strand. Each new strand is identical to its template strand. Each strand of both daughter molecules contains a mixture of old and newly synthesized DNA. The two parental strands reassociate after acting as templates for new strands restoring the parental double helix.
DNA replication is said to be semiconservative because ___ Synthesis can proceed uninterrupted (as a leading strand) in only one direction Each new DNA strand contains one parent strand and one new strand After each round of DNA replication, the original DNA strands joins None of the above
DNA replication is considered semiconservative because the________ strand will remain as half of the ________ molecule.a. antisense, DNA b. template, final DNA c. sense, mRNA d. codon, anticodon
Which of the following statements is/are TRUE for DNA Replication? Two daughter DNAs are formed, each one contains an old and new strands. When the (parent) DNA strands unwind, the 3'→ 5' strand is the leading strand while the 5'→3' strand is the lagging strand. Requires dATP, dTTP, dGTP, dCTP and Mg2+ The replisome is the biological machine responsible in replicating DNA.
Which of the following steps in DNA replication would occur second? 1.DNA molecule separates into two template strands.2.Complimentary nucleotides are added to each template strand.3.DNA molecule unwinds.4.Two DNA molecules, each with a template strand and a new strand, are formed.
Which of the following involves remarkable capacity of short segment of DNA to move from one place to another?a) DNA transpositionb) DNA replicationc) Translationd) Transcription
