Directed Aldol Synthesis: Part 2 – Syn and Anti control using Zimmerman Traxler principle
Posted on August 3, 2011 | No CommentsAldol synthesis gives rise to stereocenters in the molecule. Directed aldol synthesis is an approach in order to control the stereochemistry of the product being formed. Part 2 considers how to control whether syn products or whether anti products are formed utilizing the Zimmerman Traxler principle of stereocontrol. -
Directed Aldol Synthesis: Part 1 – Formation of E-Enolate and Z-Enolate
Posted on August 2, 2011 | 1 CommentAldol synthesis gives rise to stereocenters in the molecule. Directed aldol synthesis is an approach in order to control the stereochemistry of the product being formed. Formation of the enolate is the first step in aldol synthesis, and hence stereocontrol must begin with the first step itself. -
How Embryonic Stem Cell Lines Are Made
Posted on July 29, 2011 | No CommentsStem cells can be cultured to produce complete organs for a human being as well and hence therapies involving embryonic stem cell lines are being researched. The animation below describes the process of how embryonic stem cell lines are made from the blastocyst. -
Sanger Sequencing – Early DNA Sequencing
Posted on July 28, 2011 | No CommentsSanger sequencing of DNA (also known as the early DNA sequencing technique) utilizes early chain termination in order to sequence the DNA by utilizing a short DNA primer and di-deoxynucleotides. This animation describes the process of sanger sequencing in detail. -
Model Organisms
Posted on July 27, 2011 | No CommentsA model organism is an organism which displays certain biological phenomena similar to humans and can be studied in place of human beings in order to get insight into the phenomenon. The animation below describes some model organisms which are used by scientists and their advantages. -
How Alu Jumps
Posted on July 26, 2011 | No CommentsThe Alu gene has been implicated in several genetic disorders as well as cancers and tumors. The animation below describes how the Alu element transposes or jumps from one chromosome to another. -
GeneChips
Posted on July 25, 2011 | No CommentsGeneChips were developed in order to obtain a more complete picture of the genetic activity of the cell. The GeneChip is nothing but a specialized microarray, and the animation demonstrates how it works. -
Gel Electrophoresis
Posted on July 24, 2011 | No CommentsGel electrophoresis utilizes a gel as a sieving and anti-convective medium in order to separate molecules and proteins based on their electrophoretic mobility and their mass to charge ratio. The animation describes the process in greater detail. -
DNA Transformation
Posted on July 23, 2011 | No CommentsDNA transformation is an interesting phenomenon by which one microorganism can transfer genetic material to another microorganism. The following set of two animations goes into the details of how DNA transformation is performed and used. -
DNA Restriction and Restriction Enzymes
Posted on July 22, 2011 | No CommentsDNA restriction is a technique often useful in DNA fingerprinting. DNA restriction basically implies that there is a cut or cleavage of a particular DNA molecule.
