Bacterial Transformation - Concepts

Background In early 20th century, pneumonia was accountable for a large portion of infectious disease deaths1. In order to develop an effective vaccine against pneumonia, Frederick Griffith set out to study two different strains of the Streptococcus pneumoniae: a non-virulent strain with a rough appearance (R-strain) and a virulent strain with a smooth appearance (S-strain) due to an outer polysaccharide capsule2. This outer layer of the S-strain bacteria enabled them to withstand the host...

Bacterial Transformation ExpandIMPORTANT: In addition to wearing the appropriate personal protective equipment, be sure to take care to keep your face away from suspension cultures, and to avoid inhaling reagents. Do not touch your face while performing the experiment. Always wash your hands before and after every experiment. When you are ready to safely begin, check to make sure you have a tube or tubes of competent E. coli cells in your ice bucket. Then, transfer 50 µL from one of these tubes...

Initiation of Translation

Initiating translation is complex because it involves multiple molecules. Initiator tRNA, ribosomal subunits, and eukaryotic initiation factors (eIFs) are all required to assemble on the initiation codon of mRNA. This process consists of several steps that are mediated by different eIFs. First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...

Termination of Translation

The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...
FAQs
The value a controls horizontal displacement, while b controls vertical displacement. A positive value moves points in the corresponding positive coordinate direction, and a negative value moves them in the opposite direction. A zero value leaves that coordinate unchanged, so the pair (a, b) specifies the complete displacement applied to every point.
Every point receives the same displacement vector, so the coordinate difference between any two points stays the same. Because those relative differences do not change, distances and angles remain unchanged. Parallel lines remain parallel as well, and the figure keeps its orientation, shape, and size after the mapping.
The rule (x, y) → (x + a, y + b) lets a numerical operation predict a visible movement. Adding a to each x-coordinate and b to each y-coordinate produces the coordinates of the image. Plotting those results reveals how the algebraic rule changes the figure in space.
First, identify the translation vector and list the coordinates of each vertex. Next, add the vector components to every vertex using the same rule. Record the resulting image coordinates, then plot or connect them in the original order. Consistent application ensures that the entire polygon receives the intended displacement.
Compare an original point with its corresponding image point and calculate the horizontal and vertical coordinate changes. If the same pair of changes appears for every corresponding point, those values form the translation vector. This check helps distinguish a consistent translation from a mapping that changes points by different amounts.
Translations support coordinate-geometry problems by converting a spatial movement into an algebraic rule. They can model motion, simplify spatial relationships, and help analyze figures without changing their essential geometric properties. Comparing original and image coordinates also connects visual reasoning with calculations, making the method useful for studying mapped figures.
