Microsatellites are DNA sequences consisting of short repeats of highly variable number. Hundreds thousands of such pieces of sequences have been found throughout the human genome. Microsatellites are extremely powerful markers for distinguishing alleles at linked loci and thus can be used in linkage studies, segregation analysis and in investigating somatic loss of heterozygosity or allele imbalance in tumours.
When all cells go through prior to any type of cell division a process called DNA replication takes place. During DNA replication the cells replicate their DNA in two identical copies from the original one. As a result of this process the daughter cells generated from cell division will have a complete copy of the DNA necessary for their survival.
In 1953, when the paper of double helix structure of DNA was published by James Watson & Francis Crick, it was true to consider its applications for base pare sequencing in DNA. However, the first experimental determination of DNA sequence was only available after 15 years when Wu and Kaiser reported the partial sequence of bacteriophage lambda DNA. There are many factors contributed to the delay including the similarly chemical property of different DNA molecules; length of naturally occurring DNA molecules; only four bases in DNA sequence and no base-specific DNAases.
Blood cellular components such as erythrocytes, platelets or granulocytes are regularly used in transfusion medicine. The variability of the Human Leukocyte Antigen (HLA) is a major obstacle in the field of transplantation and transfusion medicine.
Cancer is a leading cause of death which associated with tremendous social and economic burdens. The latest World Health Organization (WHO) statistics predicted ~13.2 millionworldwide cancer related deaths by 2030, which is significantly higher from 7.6 million in year 2008.
Protein Post-Translational Modification (PTM) increases the functional variety of the proteome by covalent bonding of functional groups and proteins, also proteolytic splitting of regulatory subunits and the degradation of the whole proteins.
DNA is a double-helix with two strands running in opposite directions. Each chain is a polymer; therefore, DNA is a polymer. The monomer units of DNA are nucleotides, while the polymer is known as a “polynucleotide.”
Transcription means that the genetic informations stored in double-stranded DNA are copied or printed in the form of a singlestranded RNA molecule like mRNA, tRNA, rRNA.
Human genome comprising of approximately 3 billion bases compacted into 23 pairs of chromosomes is the blue print of life in an individual.
Prediction of drug response, both in terms of efficacy and safety, is the great challenge of modern personalised medicine.
