Methylation
|
|
Methylation A biochemical process involving the addition of chemical tags called methyl groups (-CH3) to DNA. Methylation can be a signal for a gene or a section of a chromosome to turn off gene expression and become inactive or "silent".
RELATED TERMS--------------------------------------
Biochemical
Relating to biochemistry, the application of the tools and concepts of chemistry to living systems.
DNA
Deoxyribo-Nucleic acid. DNA molecules carry the genetic information necessary for the organization and functioning of most living cells and control the inheritance of characteristics.
Methylation

Gene
1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of each species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism.
Chromosome
A structural unit within a eukaryotic nucleus that carries genes. A chromosome consists of a long, continuous strand of DNA and associated proteins.

Male factor infertility
Condition in which a male patient is infertile for such reasons as very low sperm count, sperm that cannot swim properly, sperm that are unable to penetrate the egg, or blocked sperm ducts.
Methylation
Minor H antigens
Or minor histocompatibility antigens. A group of proteins (in addition to those encoded by the major histocompatibility complex (MHC) that can cause transplant tissue rejection. Minor H antigens can cause tissue rejection even when donor and recipient are matched for MHC. Immune response to minor H antigens is far less potent than response to MHC-encoded proteins, so the rejection is a slower process.
Mitochondrial heteroplasmy
An atypical condition characterized by the presence of more than one type of mitochondrial DNA in a single individual. Normally, each individual has only one type of mitochondrial DNA, inherited from his or her mother through the egg at fertilization. (Mitochondria from the sperm are systematically eliminated by the egg at fertilization.)Cloned organisms may exhibit mitochondrial heteroplasmy (having a mixture of mitochondria from both the donor cell and the recipient egg) because this elimination system may be bypassed during the cloning process.
Mitochondrion
Plural: mitochondria. A cellular structure in the cytoplasm that provides energy to the cell. Each cell contains many mitochondria. In humans, a single mitochondrion contains 37 genes on a circular mitochondrial DNA, compared with about 35,000 genes contained in the nuclear DNA.
Monozygotic twins
Twins derived from one egg and one sperm (often called identical twins).
Morula
The preimplantation embryo 3-4 days after fertilization, when it is a solid mass composed of 12-32 cells (blastomeres). After the eight-cell stage, the cells of the preimplantation embryo begin to adhere to each other more tightly, becoming "compacted". The resulting embryo resembles a mulberry and is called a morula (Latin: morus = mulberry).
