| Within the nucleus are chromosomes that contain DNA, or deoxyribonucleic acid, genetic material unique to each individual. |
| Each chromosome carries a single strand of deoxyribonucleic acid that threads together about 1,000 genes. |
| The development of organisms, from human bodies to viruses, depends on genetic information contained in DNA, deoxyribonucleic acid. |
| In 1959 Nirenberg began his investigations into the relationship between deoxyribonucleic acid, ribonucleic acid and the production of proteins. |
| Along with several independent teams, her group is extracting DNA, or deoxyribonucleic acid, from the soil and working to clone the material. |
| Laboratory analysis of them repeatedly found signs of DNA, or deoxyribonucleic acid, the master molecule of heredity and life. |
