• DNA (Deoxyribonucleic acid) is the genetic material of cellular organisms, governs cellular activities via formation of RNA messages, stores information for specific order of amino acid in all proteins synthesized by the organism, and is stable under most terrestrial conditions.
• Natural Killer Cells are a "Third population", "Kiss of death", "Null cells", "Granular lymphocytes".
• Nucleic acids are linear polymers composed of bases, sugars, and phosphate.
• Matures to Plasma cells to produce antibodies.
• RNA (Ribonucleic acid) is composed of ribose, nitrogenous base (Pyrimidine and Purine), and phosphate group.
• Natural Killer Cells are a small population of Lymphocytes that does not express markers for T-cells or B-cells.
• Chromosomes are carriers of genetic information, thread-like material of the nucleus, and the position of the genes in a chromosome.
• Most blood group variants are results of one or more single nucleotide polymorphisms: includes gene deletion, insertion, intergenic recombination, substitution, Translocation, Duplication.
• There are around 33 blood group systems and over 300 blood antigens, the ABO, P, Lewis, H, I, and MNS are composed of antigens made up of glycoproteins or glycolipids encoded by genes that codes for glycosyltransferases, and the remaining blood group systems, the antigens are direct consequences of amino acid variation in the protein sequence.
• Genome is a unique content of genetic information.
• Gene expression is the information of the DNA made available to the cell via RNA formation, transcription is the synthesis of RNA from a DNA template, and RNA polymerase catalyzes the formation of phosphodiester bonds that links the nucleotides together to form a linear chain.
• Molecular Biology is a branch of Biology that deals with molecular structures of cells.
• Genetic polymorphism refers to sites in the genome that vary among different individuals.
