The highest resolution physical map is the complete nucleotide sequence. Prenatal Diagnosis - Examining fetal cells from the amniotic fluid, the placenta, or fetal blood for alterations in the genes or chromosomes before birth. If the DNA probe is made from a mutated gene, it can be used to determine whether someone has that genetic defect. The probe will bind to complementary parts of the patient's gene. Proteins - Large, complex molecules made from amino acids.
Protein is needed for the structure, function, and regulation of the body.
R Recessive Allele - A form or mutation of a gene that must be inherited from both parents to produce a trait or disease. Unlike DNA, RNA can leave the nucleus of the cell. This means that the draft sequence will have gaps in the sequence data and regions that contain errors or are out of order. However, the value of the draft sequence is its immediate availability for researchers worldwide. Despite such ambiguities, such draft sequence information will still have high utility for many researchers.
