If the sequence of one single strand of DNA is C-A-A-G-T-A-G-G-C-T, what is the sequence of the complementary strand? Describe the origin of each strand of the new double helices created after DNA replication. Why is DNA replication important to the growth and development of a multicellular organism? Place the following terms in the correct order from smallest to largest: Nucleosome, supercoils, coils, chromosome, DNA double helix
Below is a diagram of DNA replication as currently believed to occur in E. coli. Arrows start from numbers and end at specific points. Answer the questions relating to the locations specified by the numbers (1) Which end (5' or 3') of the molecule is here? (2) Which enzyme is probably functioning here to deal with supercoils in the DNA? (3) Which enzyme is probably functioning here to unwind the DNA?
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.
Address the general properties of the chromatin within the following types of DNA: DNA undergoing active transcription DNA within a mitotic chromosome DNA immediately after passage of the replication fork centromeric DNA
Why is DNA replication is considered a semi-discontinuous process? Explain in detail.
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.
