Protein structure
Proteins are polymers of amino acids. Each amino acid consists of an amino group, a carboxyl group, a H atom and a distinctive R group all of which are bonded…
DNA replication
DNA replication is semi conservative in that each DNA molecule produced consists of 1 old and 1 new partner. The reason for this semi conservative nature is that the original DNA strands…
SNPs
SNPS are particular nucleotide sequences that are repeated within a region of a DNA strand (called an STR locus). STR loci occur frequently in the human genome, and the number…
Genetic polymorphisms
Applied Genetics Group at NIST (characterization of genetic polymorphisms) Polymorphisms are variations in a person's DNA sequence. These may occur in an exon and result in a difference in the protein…
Recombination
New sequences of nucleotides can be generated in DNA not only by mutation, but also by the formation of new arrangements of genes by the movement of blocks of DNA.…
Genetics
Companies: 23andme (provides kits for heritage and may offer health related kits in future) Human genetics is the study of heredity in human beings. The human genome, the entirety of human…
DNA forensics
DNA forensics is the application of DNA technology to law enforcement and crime.
DNA repair
Maintaining genetic stability requires not only accurate ways to replicate DNA but also mechanisms to repair damage that occurs to DNA. The importance of such repair mechanisms is illustrated by…
