a) Suppose you label dividing cells with ^32P. In which DNA molecules will the radioactivity be incorporated if you were to look during metaphase? b) Suppose you are examining the above cells after replication. In which DNA molecules will the radioactivity be present? In one picture, draw a schematic indicating how DNA is synthesized bi-directionally. The schematic should indicate which are the lagging strands, which are the leading strands, where the RNA primers are, and the 3' and 5' orientation...

Which of the following is true regarding DNA replication (see Chapter 16 in the textbook). Check all that are correct. Question options: A) DNA ligase joins Okazaki fragments on the lagging strand. B) DNA replication results in one double helix with all parental strand and one double helix with completely newly synthesized DNA. C) Nucleases add RNA primers to start replication. D) DNA replication starts at multiple points along the eukaryotic genome. E) Helicases prevent separation of the DNA strands...

Answer the following genetics questions: a. In detail describe the process of DNA replication. Be sure to include all the major enzymes (gyrase, helicase, ligase, polymerase, primase), SSBs, replication fork, Okazaki fragments, and strand types (leading v. lagging). Draw and label a diagram of a replication bubble and replication forks. b. Describe and differentiate among the primary, secondary, and tertiary structures of a protein. To what kinds of interactions can each of these stages be ascribed? c. What are...
