Which of the following statements is correct: O The lagging strand is synthesized continuously, whereas the leading strand is synthesized in short fragments that are later joined together. The leading strand is synthesized at twice the rate of the lagging strand. The leading strand is synthesized away from the origin of replication, and the lagging strand is synthesized away from the replication fork. The leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5' end.

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?
Which of the following statements about the DNA replication is false? a. Synthesis of the new DNA strands is form 39 to 59 b.Synthesis of the new DNA strands is from 59 to 39 c. DNA Unwinds, primase adds RNA primer, DNA polymerases synthesize the new strand and remove the RNA primer d. Many initiation points exist in each eukaryotic chromosome. e. Okazaki fragments are synthesized in the opposite direction from the direction in which the replication for moves.
As the strands are synthesized in replication, which of the following is true? the leading strand is synthesized continuously from the 5' to 3' direction while the other strand is synthesized discontinuously in the 3' to 5' direction both strands are synthesized in the 5' to 3' direction the strand that shows the Okazaki fragments is synthesized in the 3'-5' direction. both strands are synthesized continuously
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
Which of the following most correctly describes a process that occurs during DNA replication? Group of answer choices Replication of the lagging strand occurs in the 5' → 3' direction—the leading strand in the 3' → 5' direction. Replication is continuous on the lagging strand and discontinuous on the leading strand. Okazaki fragments are DNA fragments synthesized on the lagging strand. DNA polymerase adds dNTP monomers in the 3′–5′ direction. Replication is continuous on the lagging strand and discontinuous on the leading strand.
What is the difference between the leading strand and the lagging strand in DNA replication? There are different DNA polymerases involved in elongation of the leading strand and the lagging strand. The leading strand is synthesized continuously in the 5' → 3' direction, while the lagging strand is synthesized discontinuously in the 5' → 3' direction. The leading strand requires an RNA primer, whereas the lagging strand does not. The leading strand is synthesized in the 3' → 5' direction in a discontinuous fashion, while the lagging strand is synthesized in the 5' → 3' direction in a continuous fashion.
Which of the following components is not involved during the formation of the replication fork? a. single-strand binding proteins b. helicase c. origin of replication d. ligase
"In a replication bubble, the same parental DNA strand serves as the template strand for leading strand synthesis in one replication fork and as the template for lagging-strand synthesis in the other fork" is true or false.
Which of the following statements about replication is false? The proofreading function of DNA polymerases involves 3’ 5’ exonuclease activity. Origins of replication are rich in G-C nucleotide pairs. A characteristic of aging cells is that telomeres become shorter. The lagging strand is synthesized in the opposite direction as the movement of the replication fork. DNA polymerase is more accurate that RNA polymerase.
For the template DNA below, which includes one labeled end of the template DNA, clearly label the following: The origin of replication The most recently added base on each strand you draw for b & c, marked with an asterisk (star). Where DNA helicase would be & direction it moves. Where DNA ligase will be needed after replication is complete.
Which of the following is not a true statement comparing prokaryotic and eukaryotic DNA replication? a. Both eukaryotic and prokaryotic DNA polymerases build off RNA primers made by primase. b. Eukaryotic DNA replication requires multiple replication forks, while prokaryotic replication uses a single origin to rapidly replicate the entire genome. c. DNA replication always occurs in the nucleus. d. Eukaryotic DNA replication involves more polymerases than prokaryotic replication.
