Semi-conservative DNA replication can be used by bacterial chromosome and plasmid both.
a) True
b) False
Homework Answers
Answer: True.
Explanation: Semi- conservative DNA replication is a model. DNA is a double strand structure, during replication each structure opens up and acts as a template for the synthesis of new complementary strand. This will result in two DNA molecules, and each DNA molecule having one old strand that is parent strand and one new strand. This is what semi- conservative DNA replication model is.
As the structure of DNA is same in all organisms bacterial chromosomes and plasmids too have semi-conservative model of DNA replication. However there may be minor modifications in each organisms according to their needs and survival.

Which of the following is NOT true about bacterial conjugation An F factor drives replication and transfer of a conjugative plasmid The genome of the bacterial chromosome in the donor cells is altered through ectopic recombination Transfer is mediated by a tube-like pilus formed between the adjacent cells Mating cells often break apart before transfer of the entire bacterial chromosome. The transferred DNA can be incorporated in the recipient cell bacterial chromosome via homologous recombination.

2. After each sentence below, note whether the sentence is true or false. If false, cross out one incorrect word in the sentence and write the correct one above it. a. DNA polymerase requires a short primer made of DNA with a 3' OH group to begin chromosome replication. b.

The bacterial replication machinery has been isolated and examined in vitro. The best way to learn about the replication apparatus is to isolate it and them examine how each part works by itself and in concert with the other parts. Kornberg and coworkers worked very hard purifying all enzymes required for replication Initiation to try and study the process in detail. They then took the bacterial chromosome and digested it and plasmid DNA with restriction endonucleases (see below). They then...
