Question 2 Plasmids are found as extra-chromosomal DNA within bacterial cells. within eukaryotic cells and they confer resistance to some antibiotics. O prokaryotic cells and offer the ability to infect all eukayotic cells. O within bacterial cells and are essential for their survival. Question 3 If a cell lacks primase O the cell will not be able to add nucleotides to lengthening DNA as primase is responsible for this step. the cell will be unable to unwind the double helix of DNA and hence will not be able to replicate the DNA. there will be no concern for bacterial cells as primase is only essential for eukaryotic cells. O the cell will be unable to initiate DNA replication as primase acts as a primer. Question 4 Phenotype refers to the physical features of an organism. O the set of genes in the genome. cannot be associated with bacterial species as we cannot 'see' them. O how DNA is replicated within a cell.

How can i explain my answers in depth in microbology for example this question: Assume that there are horizontal gene transfers between two completely different bacterial species. In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation. In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells? Explain the biological background to your answer . How do I break down the question so I answer it fully
Each species of bacteria has its own distinctive cell surface. Thecharacteristics of the cell surface play an important role in processessuch as conjugation and transduction. For example, certainstrains of E. coli have pili on their cell surface. These pili enableE. coli to conjugate with other E. coli and also enable certain bacteriophages (such as M13) to bind to the surface of the E. coli andgain entry into the cytoplasm. With these ideas in mind, explainwhich forms of genetic transfer (i.e., conjugation, transduction,and transformation) are more likely to occur between different speciesof bacteria. Discuss some of the potential consequences ofinterspecies genetic transfer.
