Why is DNA replication called semiconservative?
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.
What is the function of DNA polymerase? a. It degrades DNA in cells. b. It adds RNA nucleotides to a new strand. c. It coils DNA around histones to form chromosomes. d. It adds DNA nucleotides to a replicating strand. e. None of these.
Which of the following is not a characteristic of DNA replication? The synthesis of a new DNA strand always occurs from the 5' to 3' direction. SE O A newly synthesized DNA contains an old strand from the parent DNA and a newly synthesized DNA strand. One strand of the DNA is synthesized discontinuously in short stretches. The synthesis of DNA is unidirectional.
Which of the following statements is NOT TRUE about genomic DNA replication? O A DNA replication begins at the origin of replication and proceeds bi-directionally O B. New nucleotides can be added by the DNA polymerase only to the 3 end of the growing strand O. Synthesis of new DNA is catalyzed by the enzymes called DNA polymerases OD. DNA replication is semi-conservative OE. DNA replication proceeds continuously on both parental DNA strands.
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.

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 regarding DNA replication is FALSE. Replication of DNA is highly regulated. DNA is the only biomolecule that can be replicated. Replication is an amazingly complex process: it is amazing that can occur in a physiologically relevant time frame. The fact that DNA can be replicated allows it to serve as the genetic material. The progeny receive one strand that originated from the parent and one newly synthesized strand.
DNA replication is unidirectional because as DNA gyrase relaxes the DNA helix in one direction, tension is created in the opposite direction. True O False
Some Processes Involved in DNA Replication The replication origin is identified. DNA primase builds RNA primer. Okazaki fragments are spliced by DNA ligase. Helicases bind and uncoil the DNA double helix. RNA primer is the starting point for DNA polymerase. DNA replication ends at the telomere where DNA codes for termination. DNA polymerase adds complementary nucleotides in the 5' to 3' direction in short segments called Okazaki fragments. The sequence in which the events numbered above occur during DNA replication of the lagging strand is:
