Are human genes distributed uniformly in the genome? Is organismal biology the same as cell biology? Can somatic cells have a different number of chromosomes? Does each egg cell in a human woman have identical DNA? The genetic material is duplicated during ...

As we known,all cells in our body have the same DNA,however,even if they have exactly the same DNA,why are eyes and lungs so different?The answer lies with what DNA is and how it works.Human's DNA contains all of the information needed for making you.This information is stored in th...

Thirty-nine pairs had more than 100 differences in their genes. Gene changes, or mutations (突变), seen in the newly studied twins suggest that embryos don’t split neatly in half when twins form. Some twins may arise when a single cell or a small group of cells splits off from an ...
cells commit suicide in an expression of altruism for the greater good of the whole. On reflection, perhaps this is unexpected but perfectly logical behaviour for single celled organisms to adopt. Most yeast population studies have been performed using haploid laboratory strains cultivated under ...

Once a cancer has begun its unruly growth it will pick up more and more mutations: the cancer genome project at the Sanger Institute, outside Cambridge in England, has found that cancers can have as few as ten mutations or as many as a few hundred. Though all the cells in the cancer ...
