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.
The function of DNA polymerase I is to? Add nucleotides to the 3' end of the primer Add nucleotides to the 5' end of the primer Add nucleotides at the location of the primer after it is removed Add nucleotides on the template strand with the help of ribosomes Add nucleotides on mRNA
What is the function of the Primase enzyme? To edit out primers at the end of DNA replication To separate strands of DNA for replication To synthesize a short sequence of RNA that is complimentary to the template DNA strand so that DNA polymerase has an OH group to work on To prime the DNA to get it ready for gene expression
The function of DNA polymerase III is to? Choose below. Add nucleotides to the 3' end of the primer ?? // same// samee Add nucleotides to the 5' end of the primer Add nucleotides at the location of the primer after it is removed Add nucleotides at the ends of both primers Add nucleotides randomly on the DNA template
Some Events that May Occur during Transcription RNA polymerases detach. DNA polymerases detach. DNA polymerases proofread. RNA double helix is unzipped. DNA double helix is unzipped. DNA double helix forms again. mRNA is built in the 3′ to 5′ direction. mRNA is built in the 5′ to 3′ direction. RNA ligase fuses the Okazaki fragments. RNA polymerase binds to the sense strand. DNA polymerase binds to the sense strand. RNA polymerase binds to the antisense strand. DNA polymerase binds to the antisense strand. Listed in sequence, the events involved in DNA transcription numbered above are ___, ___, ___, ___ and ___.
DNA polymerase III adds nucleotides ________. to both ends of the RNA primer to the 5' end of the RNA primer to the 3' end of the RNA primer in the place of the primer RNA after it is removed to internal sites in the DNA template
Which of the following features is common to both DNA replication and RNA transcription? Both RNA and DNA polymerase form a sugar-phosphate bond between the 3' hydroxyl and the 5' phosphate. Both RNA and DNA polymerase require oligonucleotide priming. Both RNA and DNA polymerase incorporate deoxyribonucleotides into the growing sequence. Both RNA and DNA polymerase initiate at promoter sequences. Both RNA and DNA polymerase have extensive proofreading editing.
How is synthesis terminated in DNA Replication? a. DNA Polymerase runs out of template b. DNA Polymerase reaches an end site c. DNA Polymerase reads a stop codon d. DNA Polymerase adds a Poly-A Tail to the new daughter strand e. DNA Polymerase synthesizes a terminator sequence
What is the role of DNA ligase in the elongation of the lagging strand during DNA replication? It joins Okazaki fragments together. It stabilizes the unwound parental DNA. It synthesizes RNA nucleotides to make a primer. It unwinds the parental double helix.
Because the polymerization of nucleotides is an endergonic process, energy is required for it to occur. What does DNA polymerase use as its energy source? Group of answer choices ATP that is broken into ADP and P and released Energy from photons of light Entropy created from protein digestion Nucleotides incorporated into a growing chain provide their own energy in the form of trinucleotides
Select the characteristics/descriptions of DNA polymerase. Select ALL that apply requires a primer adds nucleotides to 3' end of DNA strand adds nucleotides to 5' end of DNA strand does not require primer has 3'-to-5' exonuclease activity that allows "proofreading" of DNA strand being made
Why is the new DNA strand complementary to the 3' to 5' strands assembled in short segments? Why is the new DNA strand complementary to the 3' to 5' strands assembled in short segments? only short DNA sequences can extend off the RNA primers DNA polymerase can assemble DNA only in the 3' to 5' direction it is more efficient than assembling complete new strands the replication forks block the formation of longer strands DNA polymerase can assemble DNA only in the 5' to 3' direction
