A number of birth defects or characteristics which consistently occur or run together in a specific individual. Any genetically determined characteristic. The formation of an RNA molecule from a DNA template through complementary base pairing reactions. Transcription occurs in the nucleus. The process in which a genetic code carried by messenger RNA directs the synthesis of proteins from amino acids.
Translocation occurs in the cytoplasm.
The presence of 3 chromosomes of one type instead of the normal two in an individual. The technique of prenatal examination of the fetus and uterus by the use of soundwaves. A series of allelic fragment lengths related to each other by a variable number of tandemly repeated DNA sequences, in an interval between two restriction enzyme sites. Because many allele sizes are possible, these loci are useful to distinguish between individuals, as in DNA fingerprinting. Females usually are not affected.
