You made a mutation in your cells in which you inhibited the formation of Ligase enzyme. What will happen to the DNA replication in the cells? – A. Nothing, DNA will replicate normally – B. Semiconservative replication will not happen – C. DNA primers will not form – D. Replication bubble will not form

You synthesized a new peptide in your lab, which is permeable to the cell membrane. When you added it to eukaryotic cells, you noticed that the cells do not divide and eventually die. Upon further analysis, you discovered that a small replication bubble forms but does not last long, and the strands come back together. What molecules do you think are affected in your cells? – A. Lysosome – B. Polymerase I – C. Polymerase III – D. Topoisomerase – E. Single-stranded binding proteins (SSBP)
