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.
Why is DNA replication called semiconservative?
What is the first step in the process of DNA replication? Which enzyme is responsible for “unzipping” the DNA double helix? Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule? Which enzyme is responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecules?
Which of the following statements are TRUE?I. DNA replication is a semiconservative process wherein the two resulting double helices consist of one new strand and one parental strand.II. The DNA strand that is used to make a complementary daughter strand is called the parental strand.III. The precursor of each new nucleotide in the DNA strand is a deoxynucleoside 3′-triphosphate.IV. The incoming nucleotide always attaches to 5′-phosphate of the previously added nucleotide

DNA replication involves a series of steps, including initiation, making primers, extension, and connecting DNA fragments. The cell uses different enzymes in a particular order to accomplish these steps. Which of the following represents the correct general order of enzyme use? A. DNA polymerases, helicase, primase, ligase B. Helicase, ligase, primase, DNA polymerases C. Helicase, primase, DNA polymerases, ligase D. Primase, helicase, DNA polymerases, ligase
Does E. coli chromosomal replication always start at one particular site? What is called? If you were given the DNA sequence of E. coli chromosome, would you be able to identify where E. coli chromosomal replication starts? What is the end of E. coli chromosome replication?
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
As a result of DNA replication two DNA molecules come into existence. Why is it not correct to assert that two “new” DNA molecules are created? What is the name given to the process concerning that fact?
in DNA replication, if the template strand is 5’-ATCCGTGTAACCTT-3’, what is the sequence of the newly synthesized DNA strand? Write the sequence from 5’ to 3’.
Why does DNA replication produce two daughter strands that are identical to each other and to the parent DNA?
Arrange the events of replication chronologically from A (first) to G (last event): -Sealing of phosphodiester linkage -Replacement of RNA primer with new DNA strand -Unwinding of the double helix -Addition of short RNA primers -Recognition of origin of replication -Synthesis of complementary DNA strand at the leading strand of the DNA -Excision of short RNA primers
