Core 2: Genetics and Inheritance

Practice flashcards for reviewing key concepts about genetics and inheritance, focusing on plasmids, binary fission, transformation, transduction, and conjugation.

A plasmid is a small, circular DNA molecule that is __ from the bacterial cell's chromosome.

Separated from the bacterial cell's chromosome.

Plasmids can replicate __ of the genomic DNA.

Independently.

Binary fission is an example of __ gene transfer.

Vertical gene transfer.

The three main steps in binary fission are __, chromosome segregation, and cytokinesis.

DNA replication.

Transformation is the uptake of __, foreign DNA by competent cells.

Naked.

Transduction is the process by which bacterial DNA is transferred from one bacterium to another via __.

A bacteriophage.

Bacterial conjugation requires __ contact between cells.

Cell-to-cell.

The __ cell is designated as F+ cell as it carries an F factor and the recipient cell is designated as F- cell.

Donor.

Generalised transduction requires infection of a bacterium by a __ bacteriophage.

Virulent.

In specialized transduction, the phage-host hybrid DNA can be incorporated through __ recombination with the recipient's chromosome.

Homologous.

The __ factor carries genes for the production of sex pili in bacterial conjugation.

F.

In the rolling circle mechanism, the nicked strand serves as a template to synthesize a __ strand.

Complementary.
