Introduction Deoxyribonucleic acid is contained in
all cells. The structure of DNA makes gene
transmission possible. Since genes are segments of
DNA, DNA must be able to make exact copies of
itself to enable the next generation of cells to
receive the same genes. The DNA molecule looks
like a twisted ladder. Each side is a chain of
alternating phosphate and deoxyribose sugar
molecules. The steps are formed by bonded pairs of
purine-pyrimidine bases. DNA contains four such
bases the purines adeni...
