Recombinant DNA. Illustration of the DNA molecule (Deoxyribonucleic Acid,showing a recombined fragment. DNA carries the inherited instructions of a living organism. Here,a segment of DNA (white,foreground) is joined to,and recombined with,a larger segment of DNA (blue,background). Recombination is used in genetic engineering to incorporate a gene sequence into a DNA strand. The DNA molecule is composed of two strands of atoms twisted into a helical shape. Each strand consists of an outer sugar-phosphate backbone (blue,white) from which nucleotide bases project and link up. The sequence of bases forms the genetic code | |
