Document Summary
Technically, what is dna: deoxyribonucleic acid: technical and chemical term, dna uses a four letter alphabet (four nucleotides, a (adenine, c (cytosine, g (guanine, t (thymine, dna has 2 strands which are complementary. Monosomy: only one copy of a particular chromosome, xo: monosomy of the x chromosome in women, turner syndrome, shortened stature, sometimes sterility, other physiological changes, only occurs in females, sterile, cannot reproduce. P is the short arm, q is the long arm bands are most often the areas where genes are located. D16s559 line to the 559th location mapped on this chromosome. Line down to dna and 16th chromosome( 2 different lines) Y chromosome: only men have them, passed on strictly from father to son, 60 million nucleotides (small, only has 78 genes, passes on purely, without mixing, no recombination. Mitochondrial dna (mtdna: mitochondria give energy to cells, each cell has 1000-2000, each mitochondria has hundreds of dna copies.
