Examines mechanisms of changing proteins; effects of mutations on protein function and survival of the organism; technique of using differences in protein structure to determine evolutionary relationship.
A three dimensional visualisation of the process which takes place in certain genes, whereby the protein-coding sections of the DNA ("exons") are interrupted by non-coding regions ("introns"). RNA splicing...
Examines constraints on 3-dimensional configuration of proteins. X-ray methods used in determining 3-D structure
Shows how amino acids are joined together to form the peptide chains of a protein molecule; how the sequence of amino acids in a protein is determined and the function of DNA and RNA in the synthesis of...
Explains how DNA controls all of the forms and functions of an entire organism and how arrangements of only four bases in the DNA molecule can carry the information for all of an organism’s features. This...
Discusses water chemistry, amino acid structure, peptide bonds, protein synthesis, secondary and tertiary protein structure, functions of proteins.
Looks at some new developments in the food industry starting with single cell proteins from mineral oil and leaf protein from lucerne. Compares the economics of producing these materials for animal feed with...
Shows structure of enzymes as evidence of mechanism; feedback inhibition; repression of enzyme synthesis.
Explains why attempting to detect the presence of protein samples directly from an electrophoresis gel is impractical, due to diffusion of the protein bends over time and the fragility of the gel itself....
MOVIETONE CARD TITLE: Leaves to Feed Millions. DESCRIPTION: A dramatic development by a British scientist could save millions of starvation deaths. A process to convert green leaves into an edible...
