<li>Origin of replication (ORI): Allows replication of the vector within the host cell.</li>
<li>Selectable marker: Allows selection of host cells containing the vector.</li>
<li>Cloning site: Allows insertion of foreign DNA into the vector.</li>

<li>Primer annealing: Cooling DNA to allow primers to bind to the target sequence.</li>

<li>Gel electrophoresis is a technique used to separate DNA fragments based on their size.</li>
<li><strong>The process involves</strong>:
<ul>
<li>Loading DNA samples onto a gel made of agarose or polyacrylamide.</li>
<li>Applying an electric current that causes DNA to migrate through the gel.</li>
<li>Smaller DNA fragments migrate faster, resulting in distinct bands on the gel.</li>

<ul>
<li>Transformation is the process of introducing foreign DNA into bacterial cells.</li>
<li>The foreign DNA often contains a selectable marker, allowing selection of transformed cells.</li>
<li><strong>Transformation can be achieved by</strong>:
<ul>
<li>Heat shock: Briefly exposing the host cells and DNA to high temperature.</li>
<li>Electroporation: Applying an electric field to create temporary pores in the cell membrane.</li>
<li>Chemical methods: Using chemicals to increase cell membrane permeability.</li>

<li>Screening is done to identify transformed cells containing the desired cloned DNA.</li>
<li><strong>Common methods for screening include</strong>:
<ul>
<li>Blue-white screening: Utilizes a reporter gene (e.g., lacZ in E. coli) to distinguish transformed cells.</li>
<li>PCR-based screening: Amplifies specific DNA sequences to confirm the presence of desired DNA.</li>
