| cancer gene | 3.95 | There are two types of cancer genes. | ||
| mouse gene | 1.97 | The structure of the mouse gene was already known. | ||
| suppressor gene | 1.91 | Tumor suppressor genes halt abnormal cell growth. | ||
| resistance gene | 1.78 | The HIV resistance gene existed when HIV appeared. | ||
| telomerase gene | 1.58 | As cells differentiate, they repress the telomerase gene. | ||
| bacterium gene | 1.51 | The corn contains a bacterium gene that makes it toxic to insects. | ||
| breast gene | 1.38 | The discovery of the breast cancer gene was announced in June. | ||
| receptor gene | 0.99 | The report of the mutated receptor gene received a similarly mixed reception this week. | ||
| tumor gene | 0.99 | Tumor suppressor genes halt abnormal cell growth. | ||
| disease gene | 0.92 | But finding disease genes is only a first step, White said. | ||
| obesity gene | 0.72 | And no obesity genes or crash diets are involved. | ||
| tumour gene | 0.72 | Tumour suppressor genes seem to be very important in colorectal carcinogenesis. | ||
| ob gene | 0.66 | That one, called the ob gene, influences appetite. | ||
| plant gene | 0.66 | This is the first time that the plant gene was identified in humans, too. | ||
| target gene | 0.59 | Could FMS itself be the target gene? | ||
| virus gene | 0.59 | The fruits produced would then carry seeds with the engineered virus gene. | ||
| counterpart gene | 0.53 | One class has counterpart genes on the X chromosome. | ||
| marker gene | 0.53 | Two others have just the marker gene, Campbell said. | ||
| suicide gene | 0.53 | Desrosiers said he doubts the suicide gene will work. | ||
| susceptibility gene | 0.53 | Suppose scientists identify two susceptibility genes for alcoholism. |
