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

DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One aspect of DNA that allows it to accurately store genetic information is the base pairing from Chargaff's first rule of the four nucleotide bases. If the A content of a DNA molecule is 18%, what are the percentages of the remaining bases? T = G = C = % % %

A space probe returns from Mars where it has collected a new microorganism. It has double- stranded DNA as its genetic material, and your studies show that it uses a semiconservative replication process. Your studies also show that DNA synthesis is continuous on both the leading and on the lagging strand. What do you conclude about the microorganism?

The final steps of DNA synthesis involve the removal and replacement of primers with DNA, and the formation of the final phosphodiester bonds of the backbone which join all the fragments into one unbroken strand of DNA.  True or false?

45. The double helix structure of deoxyribonucleic acid (DNA) is shown above. When DNA replicates, the two strands must "unzip." Which statement describes the energy requirements and forces involved? (A) Energy must be added to break the covalent bonds. (B) Energy must be added to break the hydrogen bonds. (C) Energy is released when the covalent bonds break. (D) Energy is released when the hydrogen bonds break.

In NOT more than 200 words, explain how the double-helical structure of DNA suggests a mechanism for DNA replication?

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

DNA replication is semi-conservative, this statement means that   Question 6 options:   a)  the new DNA molecules that are made are not identical to the original DNA molecule.   b)  the new DNA molecules that are made are only partially DNA since RNA primers are included.   c)  the new DNA molecules that are made are composed of one strand of the old DNA molecule and one strand of new DNA.   d)  of the two new DNA molecules made, one is entirely new DNA and one is entirely old new.   e)  the new DNA molecules that are made have a mixture of old and new DNA in each strand of the DNA duplex, randomly interspersed.

Semiconservative replication of DNA means that:   a. both daughter duplexes will be entirely new and the parental duplex will be degraded   b. each daughter duplex will have one of the original parental strands and one new strand   c. each strand of the daughter duplexes will have parts of the parental strand and parts of the new strand   d. one daughter duplex will be entirely new and the other will have both original parental strands

DNA replication is vital for successful cell division. Explain the process of DNA replication. Make sure to use the following terms: helicase, S-phase, DNA polymerase and DNA ligase, template, free nucleotides. Use the diagram if it helps you illustrate your points.
