1. Figure below shows initiation of replication fork, blue strands are template and red strands are newly synthesized molecules. Position of DNA polymerase is shown in black shaded structure. Portion of template-newly synthesized molecule junction is shown by enlarged diagram, where deoxyribonucleic acids are shown.
2. Replication fork after some time, showing leading (continuous) strand and lagging (discontinuous) strands with okazaki fragments.
3. Replication fork after the action of DNA ploymerase I,showing filled gaps (in blue among the red newly synthesized strand). Direction of replication and gap filling are indicated by arrows.
The process of DNA replication involves a variety of enzymes that interact in complicated ways. Not...
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...
11. Several enzymes and proteins participate in DNA replication. Answer the fill in the blan below bonds unwinds DNA by breaking the a. The enzyme between the nitrogenous bases bind to single-stranded DNA to stabilize it and to prevent it from reannealing to the other DNA strand. makes DNA This enzyme adds nuceotides to the end of a nucleic acid strands; therefore, it makes DNA in the to direction . DNA Polymerase cannot put two nucleotides together, instead, it adds...
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...
