Structure
of DNA - 1
“ double-stranded
molecule with double helix configuration
“ each strand
consists of:
U four
building blocks: (deoxyribonucleoside triphosphates)
]dTTP
]dCTP
]dATP
]dGTP
deoxyribose + quanine + triphosphate
sugar
base
deoxyribose + Adenine + triphosphate
deoxyribose + cytosine + triphosphate
deoxyribose + thymine + triphosphate
“ DNA
molecules consist of highly compacted units called chromosomes to which proteins are attached
“ the nucleus
of each human cell has 23 pairs of chromosomes (46 chromosomes) and constitutes the human genome.
“ DNA
molecules consist of a 3' and
5' end
