A mutation results in the production of much less DNA ligase than normal. What would be a likely consequence?
DNA replication would not be able to occur at all.
DNA replication would occur, but the leading strand would be composed of many small fragments.
DNA replication of both strands would occur slowly because the unwinding of DNA would be impaired.
DNA replication would occur, but replication of the lagging strand would take much longer than normal.
Homework Answers
A mutation results in the production of much less DNA ligase than normal will result in DNA replication, but the leading strand would be composed of many small fragments. Production of much less DNA ligase than normal will result in a decrease level of cellular DNA content and the synthesized DNA will contains numerous DNA single-strand breaks, suggesting that these cells are defective in sealing nicks generated during DNA replication and/or repair.

To study DNA replication, researchers often use bacteria that harbor a temperature sensitive mutation in one of the genes related to replication. This means that when cells are grown at lower temperatures (30°C) they are fine, but when shifted to 42°C the effect of the mutation becomes evident and that protein is no longer functional. Depending on the gene mutated, researchers observe that for some replication stops almost immediately, but for others more slowly. In this question you have a...
